The following relates to video observation, surveillance and verification systems and methods of use. The specific application may work in conjunction with surveillance systems, street cameras, personal video, in-store camera systems, parking lot camera systems, etc. and is configured to provide real time and/or post time data analysis of one or more video streams.
Companies are continually trying to identify specific user behavior in order to improve the throughput and efficiency of the company. For example, by understanding user behavior in the context of the retail industry, companies can both improve product sales and reduce product shrinkage. Focusing on the latter, employee theft is one of the largest components of retail inventory shrink. Therefore, companies are trying to understand user behavior in order to reduce and ultimately eliminate inventory shrinkage.
Companies have utilized various methods to prevent employee shrinkage. Passive electronic devices attached to theft-prone items in retail stores are used to trigger alarms, although customers and/or employees may deactivate these devices before an item leaves the store. Some retailers conduct bag and/or cart inspections for both customers and employees while other retailers have implemented loss prevention systems that incorporate video monitoring of POS transactions to identify transactions that may have been conducted in violation of implemented procedures. Most procedures and technologies focus on identifying individual occurrences instead of understanding the underlying user behaviors that occur during these events. As such, companies are unable to address the underlying condition that allows individuals to commit theft.
Surveillance systems, street camera systems, store camera systems, parking lot camera systems, and the like are widely used. In certain instances, camera video is continually streaming and a buffer period of 8, 12, 24, 48 hours, for example, is used and then overwritten should a need not arise for the video. In other systems, a longer period of time may be utilized or the buffer is weeks or months of data being stored and saved for particular purposes. As can be appreciated, when an event occurs, the video is available for review and analysis of the video data. In some instances, the video stream captures data and analyzes various pre-determined scenarios based upon automatic, user input, or programming depending upon a particular purpose. For example, the video may be programmed to follow moving objects from entry into a store and throughout the store for inventory control and/or video monitoring of customers.
In other instances, police, FBI or rescue personal need to review the various camera systems in a particular area or arena for investigative purposes, e.g., to track suspects, for car accident review, or other video evidence necessary to their investigation. As is often the case, snippets of video from various camera systems throughout the area can be critical in piecing together a visual map of the event in question. In other scenarios, an individual's habits or behaviors may become suspicious and deserved of monitoring or tracking for real-time analysis and alerts and/or post time investigative analysis.
There exists a need to further develop this analytical technology and provide real time and post time analysis of video streams for security and investigative purposes.

With reference to
Each video camera 110 connects to the computer 120 and a user interface 122 to provide a user connection to the computer 120. The one or more video cameras 110 may each connect via individual connections and may connect through a common network connection, or through any combination thereof.
System 100 includes at least one video analytics module 140. A video analytics module 140 may reside in the computer 120 and/or one or more of the video cameras 110. Video analytics module 140 performs video processing of the video. In particular, video analytics module 140 performs one or more algorithms to generate non-video data from video. Non-video data includes non-video frame data that describes content of individual frames such as, for example, objects identified in a frame, one or more properties of objects identified in a frame and one or more properties related to a pre-defined portions of a frame. Non-video data may also include non-video temporal data that describes temporal content between two or more frames. Non-video temporal data may be generated from video and/or the non-video frame data. Non-video temporal data includes temporal data such as temporal properties of an object identified in two or more frames and a temporal property of one or more pre-defined portions of two or more frames. Non-video frame data may include a count of objects identified (e.g., objects may include people and/or any portion thereof, inanimate objects, animals, vehicles or a user defined and/or developed object) and one or more object properties (e.g., position of an object, position of any portion of an object, dimensional properties of an object, dimensional properties of portions and/or identified features of an object) and relationship properties (e.g., a first object position with respect to a second object), or any other object that may be identified in a frame. Objects may be identified as objects that appear in video or objects that have been removed from video. Objects may be identified as virtual objects that do not actually appear in video but which may be added for investigative purposes, training purposes, or other purposes.
Video analytics module 140 may be positioned in camera 110 to convert video-to-video data and non-video data and the camera 110 and to provide the video data and the non-video data to the computer 120 over a network. As such, the system 100 distributes the video processing to the edge of the network thereby minimizing the amount of processing required to be performed by the computer 120.
Computer 120 includes computer-readable medium comprising software for monitoring user behavior, which software, when executed by a computer 120, causes the computer 120 to perform operations. User interface 122 provides an interface to the computer 120. User interface 122 may connect directly to the computer 120 or connect indirectly to the computer 120 through a user network.
A user behavior is defined by an action, an inaction, a movement, a plurality of event occurrences, a temporal event, an externally generated event, or any combination thereof. A particular user behavior is defined and provided to the computer 120.
An action may include picking up an object wherein the object has been placed or left at a particular location. An action may include moving a particular object such as the opening of a door, drawer or compartment. An action may include positioning (or repositioning) a body part such as placing a hand in a pocket or patting oneself repeatedly at a particular location (an indication that a weapon may be concealed). The action may include moving to a particular position, a first individual engaging a second individual and/or moving a hand, arm, leg and/or foot in a particular motion. An action may also include positioning a head in a particular direction, such as, for example, looking directly at security personnel or a security camera 110. Various other examples have been discussed hereinabove.
Inaction may include failing to reach for an object wherein an object is dropped or positioned and the individual (e.g., object) does not retrieve the dropped object. Inaction may also include failing to walk to a particular location or failure to perform a particular task. For example, confirming that a security door is locked would require the action of approaching the door and the action of striking the door to ensure that it would not open. As such, the user behavior may be defined as the inaction of approaching the door and/or the inaction of striking the door to confirm that the door will not open. Various other examples of inaction have been discussed hereinabove.
A temporal event may include the identification of a customer that abruptly leaves a store, an individual dwelling at a store entrance or exit, an individual remaining in a particular location for a time period exceeding a threshold. Various other examples of a temporal event have been discussed hereinabove.
A user may identify a particular user behavior and provide and/or define characteristics of the particular user behavior in the computer 120. Computer 120 receives non-video data from the camera 110 wherein the non-video data includes behavioral information data. The particular user behavior may be defined by a model 143 of the behavior where the model 143 includes one or more attribute such a size, shape, length, width, aspect ratio or any other suitable identifying or identifiable attribute (e.g., tattoo or other various examples discussed herein). The computer 120 includes a matching algorithm or matching module 141, such as a comparator, that compares the defined characteristics and/or the model 143 of the particular user behavior with user behavior in the defined non-video data. Indication of a match by the matching algorithm or module 141 generates an investigation wherein the investigation includes the video data and/or non-video data identified by the matching algorithm 141. Investigations are a collection of data related to an identified event, and generally document behaviors of interest. As such, investigations require further review and investigation to understand the particular behavior.
The investigation may be sent to other cameras or systems on a given network or provided over a community of networks to scan for a match or identify and alert. Matching algorithm 141 may be configured as an independent module or incorporated into the video analytics module 140 in the computer 120 or in any cameras 110. The video analytics module 140 may also include a comparator module 142 configured to compare the model 143 of the particular user behavior and the non-video data.
A particular user behavior may be defined as positioning a head toward an observation camera 110 exceeds a preset period or positioning of a head directly toward a manager's office exceeds a preset period. This particular user behavior is indicative of a customer trying to identify the observation cameras 110 in a store in an effort to prevent being detected during a theft or an employee trying to determine if a manager is observing his/her behavior. The video analytics module 140 performs an algorithm to generate non-video data that identifies the head position of objects. The video analytic module 140 may also provide a vector indicating the facial and/or eye direction. The matching algorithm 141 searches the non-video data to determine if the head position and/or vector indicating facial direction exceeds the preset period. A match results in the generation of an investigation.
With reference to
Sequencer 200 generates a time-stamp from data provided with the video and/or image data. The time-stamp may be embedded into the video and/or image data, provided as part of the video and/or image, or a time-stamp may be provided with the file containing the video and/or image data. Alternatively, sequencer 200 may be configured to receive user-entered data, included time-stamp information, associated with each input.
Sequencer 200 may additionally, or alternatively, generate a geo-location from the data provided with the video and/or image date. Geo-location information may be embedded into the video and/or image data, provided as part of the video and/or image, or provided with the file containing the video and/or image data. For example, video and/or image may contain a land-marking feature that may be used to identify the location where the picture was taken.
Sequencer 200 may additionally, or alternatively, generate field-of-view data (hereinafter “FOV data”) for video and/or image data. FOV data may be obtained from the camera location information, obtained from the information contained within the video (e.g., landmark identification) and/or entered by a user.
A user may provide the sequencer 200 with a particular time and/or timeframe and the sequencer provides all video and/or images related to that particular time. Time and/or timeframe may be selected on the timeline 310 and the image map 300 may be updated to include all video and/or image data related to the selected time and/or timeframe.
A user may additionally, or alternatively, provide the sequencer 200 with a selected location and the sequencer provides all video and/or image data related to that particular location. Selected locations may be selected on the image map 300 or provided as geo-location data to the sequencer 200.
A user may additionally, or alternatively, provide the sequencer 200 with a particular time and/or timeframe in addition to a geo-location to further narrow and isolate all video and/or image data related to that particular location.
After a particular time, timeframe and/or geo-location is used to identify video and/or image data, the user may utilize the searching algorithms, methods and system described herein to identify particular items of interest, patterns and/or individuals contained within the video and/or image data.
It is important to note that the present disclosure goes beyond facial recognition software (which may be utilized in conjunction herewith) and provides additional algorithms and analytics for tracking and/or investigative purposes as explained below. In addition, it is not necessary in certain instances that facial recognition be utilized to flag or track someone or something and the presently-described system may be employed without facial recognition software or algorithms which may prove insensitive to certain moral, federal or local laws.
The present disclosure also relates to an analytical recognition system for real time/post time object tracking based on pre-programmed parameters, e.g., real time and post time analysis, recognition, tracking of various pre-programmed (or post programmed) known objects or manually programmed objects based on shape, color, size, number of certain objects on a person(s), oddity for a particular circumstance (e.g., winter coat in 80° heat), similarity of particular object over the course of a particular time frame (similar items, e.g., backpacks, within particular area), separation of a sensitive object(s) from person for a preset period of time, odd object in particular area, objects placed near sensitive objects, similar objects being placed in similar areas and separated from person, particular color contrasts and combinations (e.g., red shirt exposed under black shirt, or white hat on black hair).
Programmed objects may include objects with a particular known shape, size color or weight (as determined by number of people carrying, gait of person carrying, how the object is being carried, etc.) or based upon a look up library of objects and mapping algorithm. These objects may be pre-programmed into the analytical software and tracked in real time and/or post time for analysis. Manually programmed objects may be inputted into the software by color, size, shape, weight, etc. and analyzed and tracked in real time and/or post time to determine abnormal conditions or for other purposes. Manually programmed objects may be uploaded for analysis in real time, e.g., facial recognition images, tattoos, piercings, logos, or other indicia as explained in more detail below. Additionally, a user generated item and/or image may be generated from video data (e.g., frame data) and/or a still image and provided for analytics. For example and as shown in the an analytical recognition system 500 of
System 500 may include video analytics module 140 that is configured to perform real time and/or post time analysis of video and tracking of every person with a backpack 510 within a particular area or within a particular camera view 505. Suspicious behavior and/or behavior of interest of one or more persons may be tracked and recorded and analyzed in either real time or post time. For example as identified in
In other example, the system 500 may flag and track in real time for alert purposes or post time analysis a person wearing a winter coat in the Summer, a long raincoat when sunny, etc. This would also be classified as an alert or abnormal condition.
The system 500 may be capable of combining pre-programmed analytics to alert for one or more (or a combination of) abnormal scenarios. For example, a person carrying a case capable of carrying an semi-automatic or automatic rifle and that person loitering outside of a sensitive building for a pre-determined period of time may be automatically flagged, tracked and an alert sent to security.
The system 500 may be capable of tracking and analyzing particular objects and the software or video analytics module 140 may be pre-programmed to identify the same objects in later obtained video streams and/or still images. For example, a person of particular importance is scheduled to have a press briefing or scheduled to arrive at a particular location at a specific time. The scheduled event is postponed (intentionally or unintentionally). The software or video analytics module 140 may be preprogrammed to recognize certain objects (or persons with objects 510 or user generated objects 535) appearing in newly generated video for the re-scheduled event. In certain instances, the original video from the original time of the scheduled event may be reviewed and a user may pre-program the software or video analytics module 140 to look for certain “repeat” objects 510 (backpacks, coats, hats, clothing, briefcases, persons, etc.) in the real time video footage of the now re-scheduled event. A person may also be classified as a loiterer and flagged for review at the later scheduled event. A warning can be sent to the security team reviewing the tapes in real time if that was a person of interest.
The video analytics module 140 may be configured to recognize abnormal patterns of behavior or unexpected patterns of behavior and alert security or investigators of potentially abnormal scenarios, events or conditions. The video may be configured for real-time analytics or post event analysis. For example, the video analytics module 140 can be programmed to recognize convergence patterns toward a particular geographical area and/or divergence patterns away from a particular geographical area. Global positioning software and vectoring may be utilized to accomplish this purpose. Recognition of convergent patterns and/or divergent patterns may be helpful in automatically recognizing potential flash mobs, mass robberies or other abnormal events. For example and as shown in
A security system 600 with the video analytics module 140 and one or more camera arrays or systems 610a-610g may be configured to recognize an abnormal number of people converging towards a particular geographical area 620 over a preset time. The video analytics module 140 may be configured to utilize vector analysis and/or image and data vector analysis algorithms and/or machine learning algorithms to assess one or more convergence patterns. Moreover, the system 600 may be configured to recognize similarities in clothing, age, articles being carried (e.g., briefcases, backpacks, other similar items) and alert security or investigators of a possible abnormal condition. This can be useful in recognizing so-called “flash mobs” or other highly sensitive situations during a parade, marathon, political speech, etc.
Divergence patterns and/or velocities may be used to identify unusual patterns of individuals departing from a particular area 620. For example, in the event of a panic-like situation the divergence velocity of individuals is expected to be greater than a preset or calculated average divergence velocity. As such, identification of one or more individuals leaving the particular area and/or situation at a velocity less than the average velocity or the panic-like velocity may indicate that the individual was not in a panic-like condition possibly due to the fact that he/she perpetrated or were aware of the particular panic-like situation. Moreover a person leaving an area with a higher than average velocity may be “running from an event”, e.g., running from a robbery or away from an upcoming explosion.
The video analytics module 140 may also be configured to monitor web traffic and/or social media sites (Facebook®, Myspace®, LinkedIN®) relating to a particular location and/or event and provide alerts of that nature to security or combine web traffic relating to an event or geographic area with video analytics that recognize convergence patterns to alert of a potential flash mob or gang robbery. The video analytics module 140 may also work in reverse and access web traffic or various social media sites when a convergence pattern is recognized and ping one or more of these sites to gather additional information to possibly uncover more pattern activity or uncover a flash mob event at a particular location.
The video analytics module 140 may also be configured to monitor web traffic or social media sites for activities that precede a particular time stamp. For example, a social media posting conveys condolences for a particular event that coincides or precedes the particular event may indicate foreshadowing of the event and indicate prior knowledge of the upcoming event.
The system 600 and video analytics module 140 may be configured to analyze video from one or more street cameras, parking lot cameras, store/mall camera, or other camera systems 610a-610g to determine pre-programmed abnormal conditions or manually programmed conditions in real time. The system 600 may be configured to provide an alert if an abnormal number of cars are converging at a particular spot (e.g., shopping mall), and couple that information with footage from the parking lot surveillance cameras to ascertain how many people are converging on a particular store or place and couple that analytic with the in-store camera to determine loitering at a particular spot at a particular time or delta time. This is typical behavior of a flash mob or gang robbery. Again, the system 600 might tie into one or more social media sites for additional information and/or confirmation.
Similarly, the velocity patterns of the approaching cars, obtained from video, and/or the velocity at which individuals depart from their cars may also be indicative of abnormal condition.
Other examples of analytics that the video analytics module 140 may perform in real time and/or post time may relate to gang-type recognition. For example, the analytical recognition system 700 of
The video analytics module 140 may be configured to provide graphical representations of numerous abnormal conditions to better facilitate recognition of patterns or very high levels (and/or predetermined levels) of one or more abnormal conditions. This may allow a higher number of patterns to be tracked and analyzed by one or more individuals. The video analytics module 140 may also recognize contact between individuals wherein the contact may be physical contact (e.g., handshake, an embrace or exchange of an object) or contact may be non-contact (e.g., engage in conversation, prolonged eye-contact or engaging in other non-physical contact that would indicate acknowledgement therebetween).
Other alert-type conditions may relate to abnormal scenarios wherein the video analytics module 140 recognizes an object being carried by an individual 705b that is unusual for a particular area. For example as shown in
With any of the aforedescribed scenarios or alerts noted herein, the video analytics module 140 may work in conjunction with a video library of images or algorithms 750 to trigger alerts or respond to queries. Additional images, such as a library images and/or user-generated images 750, may be provided as inputs to the video analytics module 140 and used to analyze video through the recognition aspects of the video analytics module 140. This may all happen in real time or during post time analysis. Again, queries may be entered depending upon a particular purpose and the system 100, 400, 500, 600, 700 and/or 800 can in real time or post time analyze video for the queried conditions.
The system 100, 400, 500, 600, 700 and/or 800 may be configured to perform three-dimensional face recognition. The system 100, 400, 500, 600, 700 and/or 800 may be manually programmed to recognize an individual or suspect 705a in an investigation (or prior felon) based on clothing type, piercings, tattoos, hair style, etc. (other than facial recognition which may also be utilized depending on authority of the organization (FBI versus local mall security)). An image of a suspect 705a may be scanned into the video analytics module 140 and items such as piercings, tattoos, hairstyle, logos, and headgear may be flagged and uploaded into the image database for analyzing later in real time or post time analysis. For example, if a thief 705a robs a convenient store and his/her facial image is captured onto one or more cameras 710, not only may his/her image be uploaded to all the store cameras 710, but other identifying information or characteristics or traits 715 as well, e.g., hair style, tattoos, piercings, jewelry, clothing logos, etc. If the thief 705a enters the store again, an alert will automatically be sent to security. Even if the system recognizes a similar tattoo or piercing pattern or logo 715 on a different person that person may be deemed a suspect for questioning by authorities. Again, this goes beyond mere facial recognition wherein that so-called different person would not necessarily be flagged and tracked.
The system 100, 400, 500, 600, 700 and/or 800 may also generate a library of individuals and/or patrons that regularly frequent or visit a particular location thereby eliminating the need to track these particular individuals and allowing the system 100, 400, 500, 600 or 700 to focus on identification and tracking of individuals not previously identified and saved in the library. The library of patrons (not shown) may also link to a Point-of-Sale (POS) system thereby validating that the individuals identified and stored in the library are regular patrons.
As best shown in
The various described systems 100, 400, 500, 600, 700 and 800 may also be utilized to identify individuals with a “no contact” condition. For example, a building resident may have a restraining order issued by a court that prevents a particular individual from being within a certain proximity. The image, e.g., 824, may be entered into the system e.g., system 800 and the video analytics module 140 may identify the individual 805 and provide notice and/or documentation to the building resident and/or the authorities. Similarly, a government-generated database 820 may be provided to the system 800 wherein the database 820 includes a library of images 824 of individuals 805 identified in a particular legally mandated registration program.
A community may choose to set up a community network of cameras 810a-810e for this purpose. New owners of local businesses may opt to upload a particular felon's image 824 for analyzing (i.e., for local alerts) on a per occurrence subscription (e.g., dollar amount), e.g., a particularly violent felon's image 824 and additional identifying information may be of particular interest to an entire community for uploading on all networked cameras 810a-810e (or even stand alone systems) while a small time shoplifter may not be of interest.
The video analytics module 140 may also utilize gait as an indicator of an individual or suspect, limp, shuffle, head angle, stride, hand sway, hand gestures, etc. A person's gait is as individual as a fingerprint and may be used to identify disguised felons. Many variables contribute to an individual gait and this information can be uploaded to the video analytics module 140 (e.g., walk velocity, step frequency, angle between feet, hand/arm position, hand/arm sway, limp, shuffle, etc.)
The video analytics module 140 may also be configured to alert security if a certain number of known images or events or habits occurs within a particular time period (e.g., self patting of particular area(s) X number of times within preset time period, patting or clenching of a known area for carrying or hiding weapons, nervous twitching or rapid head turning X number of times, leering around corners, looking at video cameras X number of times within a preset time period, etc. The video analytics module 140 may be configured to alert security or provide information to a user based on an abnormal or excessive habit or event occurring within a preset time limit or a combination of any of the events occurring within a preset time period. For example, a person walking through a store with hand clenched atop pants with rapid head turning may trigger an alert or abnormal situation. In another example, security is flagged or highlighted (or otherwise identified in a certain area(s) by the system 100, 400, 500, 600, 700 and/or 800) and a suspect leering in that direction repeatedly or repeatedly turning his/her head in that direction may trigger an alert or abnormal situation. In another example, an individual shopping and/or lingering in an area of a store that is typically an area with short dwell times (e.g., dwell time for a male in the make-up area is typically short while dwell-time for a female is typically, if not always, long).
As mentioned above, the analytical recognition system 100, 400, 500, 600, 700 and/or 800 of the present disclosure may be utilized to determine gun or weapon detection by virtue of pre-programming certain habitual behavior into the video analytics module 140 and analyzing the same (in real time and/or post time). For example, a person repeatedly grabbing a certain area known to house weapons and walking with a certain gait (e.g., walking with a limp might indicate carrying a shotgun) may be an indication of the person carrying a weapon. This information may be analyzed with other identifying information or indicia (e.g., tattoo, gang color, gang symbol, logo, etc.) to trigger an alert or abnormal situation. In another example, an individual is wearing a trench coat when it is not raining or on a sunny day in the Summer and leering or head turning. In this instance, the video analytics module 140 would need some sort of sensory input regarding rain or temperature or sunshine (light) and/or a connection to a system that provides such data. The time of day might also become a trigger or additional event that is preprogrammed into the video analytics module 140 analytics to heighten “awareness” of the video analytics module 140 when triggering alerts, e.g., very late at night or past midnight when more robberies tend to occur.
In other examples, the video analytics module 140 may allow the security personal to query the analytical recognition system 100, 400, 500, 600, 700 and/or 800 in real time or post time: “How many people with red baseball caps have entered the store or area within the delta of 5-10 minutes?”; “How many people are converging on the central fountain at this time or over this delta time?”; “How many people have lingered at the fountain for delta minutes?” Other queries may include instructions: “Scan and recognize/flag/follow/track people wearing long pants or winter coats (when 90° degree Summer day)”; “Scan and recognize/flag/follow/track people wearing red hats”; “Scan and recognize/flag/follow/track people carrying multiple backpacks”; “Scan and recognize/flag/follow/track people who have left objects (e.g., backpacks unattended)—track person over system, multiple systems, flag location of object, etc.”; “Scan and recognize/flag/follow/track people loitering near sensitive areas, leaving objects near sensitive areas—track person over system, multiple systems, flag location; and/or “Alert if a delta number of unattended objects left at preset time or over preset time”.
In another example, the video analytics module 140 may be configured to perform real-time video processing and analyzation to determine a crowd parameter (e.g., a real-time crowd count or a real-time crowd density estimation) by automated processing of the video sequence of a physical space. The video analytic module 140 may include one or more algorithms configured to determine a rate of change in the crowd parameter. The rate of change in the crowd parameter may be indicative of crowd convergence or crowd divergence.
When the rate of change in the crowd parameter exceeds a predetermined threshold, the video analytics module 140 automatically issues an alert. For example, when the rate of change in the crowd parameter is indicative of crowd convergence, the video analytics module 140 may alert security of a potential flash mob or gang robbery. The video analytics module 140 may be configured to utilize vector analysis and/or image and data vector analysis algorithms and/or machine learning algorithms to assess one or more convergence patterns.
The video analytics module 140 may be connected to an array of cameras 610a-610g organized in a network, and upon issuance of an alert each camera in the network may be utilized to track one or more objects or individuals (e.g., patrons 604a-6041 shown in
