FIELD OF THE DISCLOSURE

This disclosure relates generally to the field of data processing systems and more particularly to interaction with information on remote computers.

BACKGROUND

Robotic process automation (RPA) is the application of technology that allows employees in a company to configure computer software or a “robot” to capture and interpret existing applications for processing a transaction, manipulating data, triggering responses and communicating with other digital systems. Conventional RPA systems employ software robots to interpret the user interface of third party applications and to execute steps identically to a human user. While this approach can be quite useful in enabling RPA, it typically requires human usage of an application which can introduce errors due to mistakes and idiosyncrasies of a particular user.

SUMMARY

Methods and systems that detect and define virtual objects in remote screens which do not expose objects are disclosed herein. This permits simple and reliable automation of existing applications. In certain aspects a method for detecting objects from an application program that are displayed on a computer screen is disclosed. An image displayed on the computer screen is captured. The image is analyzed to identify blobs in the image. The identified blobs are filtered to identify a set of actionable objects within the image. Optical character recognition is performed on the image to detect text fields in the image. Each actionable object is linked to a text field positioned closest to a left or top side of the actionable object. The system automatically detects the virtual objects and links each actionable object such as textboxes, buttons, checkboxes, etc. to the nearest label object. Advanced image processing and OCR technologies may advantageously be employed. In other aspects, background noise is removed from the image before analyzing the image to identify blobs in the image. Additionally, filtering the identified blobs may comprise retrieving one or more predefined filtering criteria that cause blobs larger or smaller than predefined sizes to be filtered out. Subsequently, when the application is accessed in a production environment by a bot, interaction with the application may be simplified as the bot retrieves the stored actionable objects and in some instances be able to employ the previously recognized actionable objects.

The disclosed methods and systems permit accurate identification, and hence automation, of applications for which only a screen image may be available to an automation user, as is common where the automation user is located remotely from the system on which the application to be automated is deployed. This permits a level of automation previously only available where underlying objects in the application to be automated are available to the system employed by the automation user. Moreover, the disclosed methods and systems permit automation even where changes in the application or to hardware, such as resolution of computer monitors, can cause changes in the visual image displayed by the application to be automated.

Additional aspects related to the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the description or may be learned by practice of the invention. Aspects of the invention may be realized and attained by means of the elements and combinations of various elements and aspects particularly pointed out in the following detailed description and the appended claims.

It is to be understood that both the foregoing and the following descriptions are exemplary and explanatory only and are not intended to limit the claimed invention or application thereof in any manner whatsoever.

DETAILED DESCRIPTION

In the following detailed description, reference will be made to the accompanying drawings, in which identical functional elements are designated with like numerals. The aforementioned accompanying drawings show by way of illustration, and not by way of limitation, specific embodiments and implementations consistent with principles of the present invention. These implementations are described in sufficient detail to enable those skilled in the art to practice the invention and it is to be understood that other implementations may be utilized and that structural changes and/or substitutions of various elements may be made without departing from the scope and spirit of present invention. The following detailed description is, therefore, not to be construed in a limited sense.

The innovations described herein may find numerous uses and may be particularly advantageous in the context of an RPA system 10, as shown in FIG. 1. A user 102 interacts with an application 103 via one or more application screens, one of which is seen at 104, which is provided via a conventional computer display 105, controlled by a processor which provides via frame buffer 107, images for display on the display 105. The application 103 is provided by way of a computer system 110, which includes a processor and storage, and which may be located remotely from the user 102. The computer system 110 executes a local instance of automation controller software 106 that may be enabled by a system administrator to enable remote operation of the application 103, such as by user 102.

In certain environments, the information provided by application 103 may contain sensitive information, the distribution or viewing of which may be subject to various regulatory or other restrictions. Automation controller 106, resident on computer system 110, operates in conjunction with RPA system 10, to interact with computer system 110. The RPA system 10 sends automation commands and queries to the automation controller 106, while respecting the security compliance protocols of computer system 110. In certain embodiments, a compliance boundary 112 may be implemented in connection with remote access module 114. Compliance boundary 112 represents a logical boundary, across which, any transfer of data or other information is controlled by agreements between parties. In certain embodiments, remote access module 114 may operate to prevent RPA user 102 from performing certain tasks on system 110, by way of example and not limitation, copying files, loading cookies, or transmitting data from computer system 110, through or beyond compliance boundary 112 via the internet or via any other output device that would violate the security protocols established by the computer system 110. The remote access module 114 may take the form of remote desktop products available from Citrix or Microsoft, which permit connection to a remote computer, such as computer system 110, to establish a communication link between system 10 and system 110 to permit apps, files, and network resources to be made available from computer system 110 to computer system 10.

The RPA system 10 implements a bot creator that may be used by RPA user 102, to create one or more bots that are used to automate various business processes executed by one or more computer applications such as application 103. The term “bot” as used herein refers to a set of instructions that cause a computing resource to interact with one or more user level computer applications to perform tasks provided by the one or more user level computer applications. Once created, the bot may be employed to perform the tasks as encoded by the instructions to interact with one or more user level computer applications. RPA user 102 may access application 103 remotely and may see the same screen 104 as seen by a user that may be located proximate to the computer system 110. Remote access module 112 may be configured to provide to user 102 only screen images generated by application 103. In such an instance, the bot creator employed by the user 102 will not be able to access any user interface level objects that may be employed by the application 103, such as HTML document models or an accessibility API provided by an operating system.

Conventionally, user 102 may manually identify fields provided by application 103. In the embodiments disclosed herein, RPA system 10 operates to automatically identify fields provided by application 103. A screen capture engine 120 operates conventionally to generate image file 121-1 by capturing an image displayed on computer screen 105 by operation of application 103. As will be appreciated by those skilled in the art, screen capture engine 120 operates by accessing frame buffer 107 employed by computer system 10. The frame buffer 107 contains a bitmap, a frame of data, of the image currently displayed on computer screen 105. The computer system 110 may be separate from or part of smart screen system 10.

The fingerprint generator 119 analyzes the image file 121-1 for various objects, such as automation controls (markers) and their locations. The combination of various objects, object metadata, properties and types, and location on the screen is used to generate a unique set of keys that can together represent a “fingerprint” or signature 121-2 of that screen that assists the automation application to recognize that specific screen, among a set of any other possible screens, as disclosed in pending patent application entitled “System And Method For Resilient Automation Upgrade” filed in the U.S. Patent Office on Aug. 25, 2015 and assigned application Ser. No. 14/834,773, and pending patent application entitled “System and Method for Compliance Based Automation” filed in the U.S. Patent Office on Jan. 6, 2016 and assigned application Ser. No. 14/988,877, which applications are hereby incorporated by reference in their entirety. The signature 121-2 is stored to a signature database corresponding to the application 103.

The image file 121-1, representing image 104, as captured by screen capture engine 120 is shown in further detail in FIG. 2A. The image file 121-1 may be encoded as a conventional image file and contains a number of objects which may be used for providing data to or receiving data from a user. Two objects are seen at 201 and 204. Object 201 is a first name field containing a label 202 “FirstName” and a data entry field 203 into which a user may enter data corresponding to the “FirstName” label 202. Object 204 is a last name field containing a label 205 “Lastname” and a data entry field 206 into which the user may enter data corresponding to the “Lastname” label 205. The image in image file 121-1 also includes a header image 208. Objects 201 and 204 are generated by application 103 which associates data field 203 with label 202 and data field 206 with label 205. These objects, and their associated labels and data fields are not discernible as such in the image in image file 121-1 which is a conventional image encoded file. The system 10 advantageously operates to automatically identify objects such as objects 201 and 204 in the image file 121-1.

The image in the image file 121-1 is enhanced by image enhancer 122 to remove background noise that may be contained in the image file 121-1, and the results are stored in file 123. For example, certain screens from which image 104 is captured may contain background colors or watermarks upon which the image 104 is overlayed. Furthermore, a document image may exist with a wide variety of fonts, fonts sizes, background patterns, and lines (e.g., to delineate table columns). Image enhancer 122 in certain embodiments operates conventionally to transform the image file 121-1 from the color space to the background space and to remove background noise from the image file 121-1 to generate image file 123. The image file 123 contains an enhanced version of the image in image file 121-1. This increases the likelihood of correct recognition of automation control elements in the image file 121-1. For example, if the image file 121-1 contains an automation control in the form of a radio button, the conversion from color to black and white and the background noise removal increases the likelihood of recognition of the radio button.

Image file 123 is processed by field detection module 124 to generate, as shown in FIG. 2B, a binarized image 210 with objects 201 and 204 recognized as blobs (binary large objects). Field detection module 124 employs a blob (rectangle) area detection algorithm to detect all the blobs in the file 123. Field detection module 124 further filters unwanted blobs like very small or very big blobs to generate the actual blob objects which are actionable objects 201, 204 as shown in the binarized image 210. In certain embodiments, multiple detection algorithms may be used to increase the likelihood of correct detection. For example, each detection algorithm may provide a confidence score and successive detection algorithms may be used until a confidence score above a predetermined threshold is attained. In certain embodiments, pretraining may be performed with a set of training images to increase the chances of proper detection. In certain embodiments, the field detection 124 and text detection 126 modules employ ongoing training to increase accuracy with further usage. In such training, the user may confirm, at times, the result provided by the modules 124 and 126 to increase the training input. In one embodiment, the field detection module 124 may operate as described in the patent application entitled “Automatic Key/Value Pair Extraction From Document Images Using Deep Learning” filed in the U.S. Patent Office on Dec. 29, 2017 and assigned application Ser. No. 15/858,976, which application is hereby incorporated by reference in its entirety.

The image file 123 is also processed by text detection module 126 to generate a binarized image 125, shown in FIG. 2C with detected text fields 202 and 205. The text detection module 114 may employ a conventional OCR program, such as the Tesseract Open Source OCR Engine available from GitHub (https://github.com/tesseract-ocr/tesseract). In one embodiment, the OCR capability may operate as described in the patent application entitled “Optical Character Recognition Employing Deep Learning With Machine Generated Training Data” filed in the U.S. Patent Office on Dec. 21, 2017 and assigned application Ser. No. 15/851,617, which application is hereby incorporated by reference in its entirety. The described system employs a Deep Neural Network (DNN) to automatically recognize text strings within scanned images.

As seen in FIGS. 2B and 2C, the representation of the image operated on by modules 124 and 126 is rendered on a blank canvas (with no noise) and preserves the X, Y coordinates of the labels and fields. Backgrounds, patterns, and lines from the original image may also be dropped to result in an image that is noise free, uniform font rendering of the original document providing a simplified image. In employing a system utilizing a Deep Neural Network (DNN) as described in the aforementioned patent application, this pre-processing advantageously reduces the statistical distribution of input images and facilitates learning by the DNN.

The blobs recognized by module 124 and text detected by module 126 are linked by smart linking engine 118 by linking each blob to its nearest text field on the left or top side. This may be performed by retrieving common patterns and applying them to link labels to values. Certain embodiments may utilize machine learning to detect patterns, and to do so on an ongoing basis to increase accuracy. In certain embodiments pretraining may be employed to increase accuracy from the outset. By this auto linking capability, the system 10 detects and identifies the same objects even if the location of the text fields changes. Because of the normalization, the same pattern can be recognized at any scale so the system 10 can also identify the correct fields even if the scaling of the screen changes.

FIG. 2E illustrates output of smart linking engine 128. As seen, data entry field 203 is linked with the nearest recognized text field to the top or left which is FirstName label 202 containing recognized text “FirstName”. Data entry field 206 is linked with the nearest recognized text field to the top or left which is Lastname label 205 containing recognized text “Lastname”. The smart linking engine 128 generates a dynamic screen 129, shown in FIG. 2E, with linked fields.

The smart screen 129 includes the image+recognized object (labels and values), which are sometimes referred to collectively as automation or actionable objects. Each automation object has associated with it custom automation controls, which can take the form of a drop down, radio button etc. The knowledge of the type of automation control permits the RPA system 10 to identify the type of input required for each automation control.

FIGS. 3A, 3B and 3C are flowcharts that show the operation of a bot runner 301 deployed pursuant to creation of the bot in conjunction with the system 10. In one embodiment, the process and mechanisms described in conjunction with FIGS. 1 and 2A-2E are performed upon each operation of bot runner 301. FIGS. 3A, 3B and 3C illustrate an alternative embodiment of operation of bot runner 301 in which a comparison of the fingerprint of each screen is performed to determine if a stored smart screen 129 corresponding to the active screen being processed by the bot runner 301 may be employed. Application screen 104 may be generated and accessed as described in connection with FIG. 1. In FIG. 3A, the screen 104 is captured by the screen capture engine 120 in the manner as described in FIG. 1 to generate image file 121-1′ which is then processed by fingerprint generator 119 as described in connection with FIG. 1 to generate signature 121-2′. The signature 121-2′ is compared with signatures stored in Stored Screen Signature database 303 at 304 against stored signatures. If a match is identified between the signature corresponding to the application screen 104 currently being displayed by application 103, then the screen 104 currently being processed by bot 301 is the same as a smart screen 129 that has been generated and stored by system 10, the stored smart screen 129 corresponding to the screen 104 currently being processed by bot 301 may be retrieved, employing the signature 121-1′, which will correspond to signature 121-1, as shown at 306. The retrieved smart screen 129 may be used by the bot 301 at 308 to process the application screen 104. As seen, in such an instance, the further processing of the image file 121-1 is not necessary, thus saving processing time and power.

FIGS. 3B and 3C illustrate screens that contain the same fields and labels as in FIG. 3A but with different placement, and hence illustrate another benefit of smart screens. As seen in FIG. 3B, the positional relationship between objects 201 and 204 has changed, with LastName label and field, 205, 206 being to the right of the FirstName label and field 202, 203. As in FIG. 3A, the image 104 is captured by screen capture engine 120 to generate image file 121-1′. Fingerprint generator 119 generates signature 121-2′ which is then compared with signatures stored in stored screen signature database 303 at 304 against stored signatures. In this case, because the positional relationship of the fields 201 and 204 has changed, the signatures 121-2 and 121-2′ will differ. Consequently, as seen, the image file 121-1′ is processed as image file 121-1 in FIG. 1 to generate a new smart screen 129′, which is stored to stored screen signature database 303 and which is then used at 308 to process the application screen 104 currently being processed by bot runner 301.

FIG. 3C shows another example where the sizing and shading of the fonts and fields has changed somewhat, as may occur on a lower resolution screen. In such a case the signature 121-2″ will not match any signature in the stored screen signature database 303 at 304 and hence the image file 121-1 will be processed as image file 121-1′ as described in connection with FIG. 3B. As seen, visual changes in the labels and fields of a recognized screen for which a smartscreen has been generated result in the same accuracy as if the underlying objects on the screen image were exposed to the RPA system.

Some examples of automation objects are text fields, radio buttons, drop downs, and tabular data. In some embodiments, the system 10 may use a combination of image recognition and object recognition in a sequence to improve successful recognition. The representation of the data structures such as image file 121-1, signature 122-2, and the outputs of the various modules such as 125 and 127 may take a variety of forms such as individual files stored within a file system or may be stored within a single file or may be stored and managed by a database or may take other forms.
