This invention relates to digital imagery and more particularly to reducing visual perceptions of digital generation and providing mark making tools simulating physical systems.
Digital graphics and digital image editing are the processes of creating and/or modifying digitally generated or digitally acquired and stored image data. Using specialized software programs, users may create, generate, manipulate, edit and transform images in a variety of ways. These digital image editors may include programs of differing complexity, such as limited-purpose programs associated with acquisition devices (e.g., digital cameras and scanners with bundled or built-in programs for managing brightness and contrast); limited editors suitable for relatively simple operations such as rotating and cropping images; and professional-grade programs with large and complex feature sets. Similarly, digital graphics editors may include programs of differing complexity, such as limited-purpose programs associated with acquisition devices (e.g., digital cameras and scanners with bundled or built-in programs for managing colour balance or applying specific graphics effects); limited editors suitable for relatively simple graphics generation (e.g., for example as part of general suites of software for business and/or residential users); and professional-grade programs with large and complex feature sets (e.g., simulating different artistic formats such as watercolour, calligraphy, pastels, oils, etc. with various applicators including various brushes, pens, air brushes, markers, sponges and knives).
Digital graphics and digital images may include, for example, “formatted” graphics and/or graphics data for use in generating an image with a digital graphics editor suite prior to “printing” the final or interim image. Accordingly, such graphics and images may include raster graphics, vector graphics, or a combination thereof. Raster graphics data (also referred to herein as bitmaps) may be stored and manipulated as a grid of individual picture elements called pixels. A bitmap may be characterized by its width and height in pixels and also by the number of bits per pixel. Commonly, a colour bitmap defined in the RGB (red, green blue) colour space may comprise between one and eight bits per pixel for each of the red, green, and blue channels. Another commonly used representation is a CMYK colour space. In these and other colour space representations, an alpha channel may be used to store additional data such as per-pixel transparency values (or the inverse-opacity values). For example, per-pixel data representing paint on a brush tool or on a canvas may include a set of colour values (e.g., one per channel) and an opacity value for the paint. In contrast vectors graphics are generally characterized by the use of geometrical primitives such as points, lines, curves, and shapes or polygons, all of which are based on mathematical expressions, to represent images along with boundary information (e.g. stroke line style and colour) and fill information (e.g. fill style and colour).
An operation often provided by digital graphics and digital image editors is the use of a virtual “paintbrush” (also referred to herein as a “brush”, “brush tool”, or mark making tool) to modify a digital image by depositing virtual paint or virtual ink. Various prior approaches have attempted to model a real-world brush and its behavior in the context of such an operation. For example, a two-dimensional (2D) raster image may be created to represent the shape of the brush as it contacts the canvas, and the 2D image may be stamped repeatedly along the input path. In another approach, a vector representation of the brush tip has been used instead of a 2D raster image.
Some existing digital painting applications create strokes by repeatedly applying a stamp at incremental positions along a path. The stamp consists of a 2D array of pixels that represent what the “brush” looks like at an instant in time. By repeatedly applying the stamp at close spacing, the effect of the brush being dragged continuously across the canvas is created, in the form of an elongated stroke. Some existing applications provide multiple settings for users to control the appearance of the stroke, e.g. size, opacity, mark making tool, and brush style. However, such applications led to uniform marks being made by the mark making tool along the stroke as the same process as applied by the software application at each point along the stroke. Accordingly, most existing applications in order to increase the realism of strokes by simulating varying user tool handling, pressure, angle of tool, etc. provide for the application of predefined functions and/or jitter to the values of the mark making tool within the stroke. Predefined functions address, for example, the initial or final stages of a stroke for the application of a brush to canvas whilst jitter addresses the intervening section of the stroke. In this manner, a brush stroke may be simulated as having increasing pressure at the beginning of stroke, some variability in pressure during the stroke, and decreasing pressure at the end of the stroke.
However, a problem with this approach is that the results can often yield, either through combining it with variations in other aspects of the stroke or solely, to strokes with mark making tools that are rendered by the software application being unnatural and appearing artificial despite the goal of the software application being to simulate as realistically as possible physical graphics image generating techniques such as painting with watercolours. Accordingly, it would be beneficial to provide either users or the software application with a mechanism to remove or reduce artifacts indicative of artificial generation, e.g. rapid transitions.
In a wide variety of applications the graphic images being generated and/or manipulated refer to imagined environments or have elements that are physical in nature. For example, science fiction art can represent anything from an alien character through to an imagined view of a galaxy, solar system etc. Accordingly, it would be beneficial to provide users with a range of mark making tools that do not mimic a mark making tool such as a brush, air brush, pen, etc. but rather represent marks made by mark making tools comprising multiple elements following physical laws.

Accordingly, within the embodiments of the invention described below and in respect of
As noted supra prior art GESGEAPs in order to improve realism within graphical images generated and/or modified by users with the GESGEAPs mark making tools provide automatic generation options in response to the user's stroke with the mark making tool. Whilst many, of these automatically generated aspects of the user's stroke do indeed add perceived realisms such as varying brush pressure on application/removal from a canvas and/or paper or the abrupt application from activation of a spray can nozzle for example. However, in many instances these automatically generated effects within the stroke are implemented through the application of random behaviours to the strokes which actually appear less realistic as they reflect instances that a user, for example, painting with watercolours or oils, could not achieve. Accordingly, the inventors have established a methodology of automatically adding noise to the computer generated mark making tool stroke allowing aspects of the mark making tool generated to be varied. The inventors have associated the terms “feature jitter” and “jitter smoothing” to the concept and refer to mark making tools with such jitter smoothing as jitter mark making tools and may be denoted within a GESGEAP by the addition of “jitter” within the mark making tool nomenclature to denote mark making tools with this feature according to embodiments of the invention.
For example, within Corel™ Painter 2015, such a series of mark making tools according to embodiments of the invention are provided within different categories of mark making tools including:
The user may through a user interface, i.e. pop-up menu, associated with their selected mark making tool adjust the jitter smoothing applied to the randomness of their mark making tool impressions given them a more natural, organic look. Accordingly, the user may control the amount of jitter that their brush produces and, in general, the jitter control the user can modify are determined by the jitter brush variant the user selects. For example, if the user selects “Coarse Spray Jitter” variant from the Airbrushes category then the user can adjust the following characteristics:
Other mark making tool controls with jitter control may include, but are not limited, to Grain, Size, Angle, Color Expression, and Impasto. Referring to

The jitter feature/jitter smoothing acts differently to smoothing as evident from Equations (1) to (3) below. Referring to Equation (1) the value of a feature characteristic of a mark making tool, , is the sum of an initial value,
0, and a randomly generated value having upper and lower limits wherein the randomly generated value is determined in dependence upon an expression, e.g. sequentially generated for each impression of the mark making tool or element of the mark making tool. In contrast, smoothing as defined in Equation (2) takes the current generated value and then applies an average value over a number of applications of the mark making tool or element of the mark making tool. Accordingly, the randomness is smoothed out. In contrast, the feature jitter function as defined, for example, by Equation (3) adds a noise value to the sum of an initial value,
0, and a randomly generated value having upper and lower limits wherein the noise value added is dependent upon the feature jitter setting established within the GESGEAP automatically by the GESGEAP or manually by the user. Equations (1) to (3) are exemplary equations only to demonstrate the prior art in Equations (1) and (2) and the invention, Equation (3). It would be evident that a variety of mathematical processes for the addition of a noise function to a randomly generated characteristic of a mark marking tool or effect generated by a mark making tool may be employed without departing from the scope of the invention.

Examples of marks generated by a pair of spring based mark making tool presets according to embodiments of the invention within a GESGEAP are depicted in
Flow particle mark making tools emit short-lived particles which “flow” from the centre of the mark making tool across the workspace and gradually fade. In effect they may be considered to resemble rockets or fireworks which as they flow encounter forces that change their path resulting in chaotic or controlled movement according to the force and its characteristics. Alternatively, they may be thought of as short-lived particles of a fluid. As such flow mark making tools are easily influenced by force, chaos, and flow maps as evident from the figures and descriptions below. As evident from the flow menu depicted in second image 500B in

Similarly, all particle mark making tools described within this specification, flow, gravity and spring, also share global chaos and local chaos as common controls. Global chaos refers to the chaos applied to all particles equally so that they move chaotically but in unison. Local chaos then applies chaos randomly to individual particles within the mark making tool. Each of the global chaos and local chaos also has an associated smoothing control for smoothing the chaos for a more organic look and each of the global and local chaos may be associated with an expression, e.g. global chaos may be direction of controller motion whilst local chaos is velocity of controller or vide-versa or other combinations according to the characteristics of the mark making tool controller.

It would be evident that the actual setting of the global and/or local chaos values may be set at any integer value between 0% and 100% using a control such as the slider depicted in the images or alternatively the range may be specified by other means and/or the user may enter either a range value numerically or the count directly numerically.

A force (flow) map as described and depicted in respect of embodiments of the invention include, but are not limited to, data associated with a one dimensional data set, two dimensional data set, or a three dimensional data set or a subset of a N-dimensional data set. For example, one dimensional data may be velocity (i.e. speed of user stroke motion), direction, pressure (e.g., stylus upon tablet measuring pressure/force as well as location, motion, wheel, tilt, bearing, rotation, source of the gesture, or randomly generated. Alternatively, a force (flow) map may be derived from an axis or multiple axis data associated with, for example, an accelerometer or accelerometer derived data, tracked motion of a user, and the tracked motion of an object or array of objects. A force (flow) map may also be derived from an external image, an external image source, a GESGEAP acquired image, external audiovisual source, external audiovisual content, external multimedia source, external multimedia content, biometric data of a user, and an item or items of environmental data. Within other embodiments of the invention the force (flow) map may be generated via a mathematical formula or mathematical formulae in which case no storage of the force (flow) map may be required although a generated “map” may be cached temporarily for use to remove the need for repeated recalculation of the force (flow) map.
Third to seventh images 1610 to 1630 respectively depict the same Flow Fur Tail mark making tool applied to a different flow map at weightings of 0%, 25%, 50%, 75%, and 100% respectively. In contrast eighth to thirteenth images 1650 to 1675 respectively depict the same Flow Fur Tail mark making tool applied to a different flow maps with constant 50% weighting. Tenth image 1660 and third to seventh images 1610 to 1630 respectively were actually generated with the same flow map but at two different scales for the tenth image 1660 and the third to seventh images 1610 to 1630 respectively.
Gravity particle mark making tools create sweeping marks that shrink and grow with movement. The particles of a gravity particle mark making tool effect the movement of planetary system such that the motion of the particles are influence by velocity, acceleration and other forces. Depending upon mark making tool stroke speed, for example, particles may stay tight within the mark making tool or they can be pulled apart by forces, inertia, etc. As such gravity particle mark making tools are influenced by forces and flow maps for example as less by chaos.

Correspondingly as depicted in fifth and sixth images 2350 and 2360 low global chaos and high local chaos results in particle configurations that are centered close to one another but the specific particle distributions are now different and no apparent structure of the mark making tool appears. This is then accentuated as evident from seventh and eighth images 2370 and 2370 where high global chaos with high local chaos results in substantial displacement between the mark making tools and different particle distributions within each mark making tool impression.
Within the descriptions supra in respect of embodiments of the invention particles may be short-lived particles generated at least one of at the initial selection of the mark making tool, at the initial use of the mark making tool, and during use of the mark making tool. Alternatively, the lifetime (or half-life) and rate of renewal of the particles may be set through a setting of the mark making tool. Similarly physical and/or non-physical links between particles, such as springs for example, may be short lived springs generated at least one of at the initial selection of the mark making tool, at the initial use of the mark making tool, and during use of the mark making tool. Alternatively, the lifetime (or half-life) and rate of renewal of the springs may be set through a setting of the mark making tool such that whilst initially bound over the stroke the particles become unbound. Further, such physical and/or non-physical links between particles, such as springs for example, may be connected to the same sub-set of the plurality of particles during the use of the mark making tool or alternatively they may be connected to different sub-sets of the plurality of particles during the use of the mark making tool.
Specific details are given in the above description to provide a thorough understanding of the embodiments. However, it is understood that the embodiments may be practiced without these specific details. For example, circuits may be shown in block diagrams in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments.
Implementation of the techniques, blocks, steps and means described above may be done in various ways. For example, these techniques, blocks, steps and means may be implemented in hardware, software, or a combination thereof. For a hardware implementation, the processing units may be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, other electronic units designed to perform the functions described above and/or a combination thereof.
Also, it is noted that the embodiments may be described as a process which is depicted as a flowchart, a flow diagram, a data flow diagram, a structure diagram, or a block diagram. Although a flowchart may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be rearranged. A process is terminated when its operations are completed, but could have additional steps not included in the figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination corresponds to a return of the function to the calling function or the main function.
Furthermore, embodiments may be implemented by hardware, software, scripting languages, firmware, middleware, microcode, hardware description languages and/or any combination thereof. When implemented in software, firmware, middleware, scripting language and/or microcode, the program code or code segments to perform the necessary tasks may be stored in a machine readable medium, such as a storage medium. A code segment or machine-executable instruction may represent a procedure, a function, a subprogram, a program, a routine, a subroutine, a module, a software package, a script, a class, or any combination of instructions, data structures and/or program statements. A code segment may be coupled to another code segment or a hardware circuit by passing and/or receiving information, data, arguments, parameters and/or memory content. Information, arguments, parameters, data, etc. may be passed, forwarded, or transmitted via any suitable means including memory sharing, message passing, token passing, network transmission, etc.
For a firmware and/or software implementation, the methodologies may be implemented with modules (e.g., procedures, functions, and so on) that perform the functions described herein. Any machine-readable medium tangibly embodying instructions may be used in implementing the methodologies described herein. For example, software codes may be stored in a memory. Memory may be implemented within the processor or external to the processor and may vary in implementation where the memory is employed in storing software codes for subsequent execution to that when the memory is employed in executing the software codes. As used herein the term “memory” refers to any type of long term, short term, volatile, nonvolatile, or other storage medium and is not to be limited to any particular type of memory or number of memories, or type of media upon which memory is stored.
Moreover, as disclosed herein, the term “storage medium” may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other machine readable mediums for storing information. The term “machine-readable medium” includes, but is not limited to portable or fixed storage devices, optical storage devices, wireless channels and/or various other mediums capable of storing, containing or carrying instruction(s) and/or data.
The methodologies described herein are, in one or more embodiments, performable by a machine which includes one or more processors that accept code segments containing instructions. For any of the methods described herein, when the instructions are executed by the machine, the machine performs the method. Any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine are included. Thus, a typical machine may be exemplified by a typical processing system that includes one or more processors. Each processor may include one or more of a CPU, a graphics-processing unit, and a programmable DSP unit. The processing system further may include a memory subsystem including main RAM and/or a static RAM, and/or ROM. A bus subsystem may be included for communicating between the components. If the processing system requires a display, such a display may be included, e.g., a liquid crystal display (LCD). If manual data entry is required, the processing system also includes an input device such as one or more of an alphanumeric input unit such as a keyboard, a pointing control device such as a mouse, and so forth.
The memory includes machine-readable code segments (e.g. software or software code) including instructions for performing, when executed by the processing system, one of more of the methods described herein. The software may reside entirely in the memory, or may also reside, completely or at least partially, within the RAM and/or within the processor during execution thereof by the computer system. Thus, the memory and the processor also constitute a system comprising machine-readable code.
In alternative embodiments, the machine operates as a standalone device or may be connected, e.g., networked to other machines, in a networked deployment, the machine may operate in the capacity of a server or a client machine in server-client network environment, or as a peer machine in a peer-to-peer or distributed network environment. The machine may be, for example, a computer, a server, a cluster of servers, a cluster of computers, a web appliance, a distributed computing environment, a cloud computing environment, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. The term “machine” may also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.
