Context processor for video analysis system
Embodiments of the present invention provide a method and a system for mapping a scene depicted in an acquired stream of video frames that may be used by a machine-learning behavior-recognition system. A background image of the scene is segmented into plurality of regions representing various objects of the background image. Statistically similar regions may be merged and associated. The regions are analyzed to determine their z-depth order in relation to a video capturing device providing the stream of the video frames and other regions, using occlusions between the regions and data about foreground objects in the scene. An annotated map describing the identified regions and their properties is created and updated.

Rendering successive frames in a graphic object system
Disclosed is an imaging engine system (699) generally intended for the reproduction of graphical object images using apparatus having limited computing resources, such as so-called “thin clients”. Numerous developments of traditional image processing and rendering enable high quality image generation. One such development takes advantage of temporal coherence between one frame in an animation sequence and the succeeding frame. In particular, there will often be some edges (233, 235) of graphical objects that remain “static” across several contiguous frames. One example of this includes those edges used to draw image background detail. Another development performs antialiasing during scan line rendering of a graphic object image where sub-pixel resolution coverage bit-masks (A-buffers 29-34) are generated for a limited number of scan lines at a time. Preferably the A-buffers are generated for only one pixel at a time. Another development relates to rendering a scan line of a graphic object image in a scan line renderer for a span of pixels lying between two x-order consecutive edges intersecting the scan line. For the span of pixels, this development maintains a subset of depths present in the rendering, the subset being those depths that are present on the span and being maintained in depth order (590) and subject to removal of depths where the corresponding depth is no longer active. In another development a compositing stack (6101-6107) of image layers to be rendered in a raster scan fashion is simplified. Rendering is operable over a run of two or more pixels within which a relationship between graphical objects contributing to the layers does not change. The layers are first divided into groups (6110, 6112, 6114), with each group being separated by a layer having variable transparency (6111, 6113). For a top one of the groups, layers having constant colour in the run are reduced to a single equivalent colour (6115, 6116, 6117) having an associated accumulated contribution. Many other developments are disclosed.

ActiveUS9142056B1Texturing/coloringCathode-ray tube indicatorsBrush strokeIntersection of a polyhedron with a line
Rendering 3D paintings can be done by compositing brush strokes embedded in space. Image elements are rendered into an image representable by a pixel array wherein at least some of the image elements correspond to simulated painting strokes. A method may include determining stroke positions in a 3D space, determining stroke orders, and for each pixel to be addressed, determining a pixel color value by determining strokes intersections with a view ray for that pixel, determining a depth order and a stroke order for intersecting fragments, each fragment having a color, alpha value, depth, and stroke order, assigning an intermediate color to each of the fragments, corresponding to a compositing of nearby fragments in stroke order, and assigning a color to the pixel that corresponds to a compositing of the fragments using the intermediate colors assigned to the fragments. The compositing may be done in depth order.

Method of tracking objects in a video sequence
A video surveillance system (10) comprises a camera (25), a personal computer (PC) (27) and a video monitor (29). Video processing software is provided on the hard disk drive of the PC (27). The software is arranged to perform a number of processing operations on video data received from the camera, the video data representing individual frames of captured video. In particular, the software is arranged to identify one or more foreground blobs in a current frame, to match the or each blob with an object identified in one or more previous frames, and to track the motion of the or each object as more frames are received. In order to maintain the identity of objects during an occlusion event, an appearance model is generated for blobs that are close to one another in terms of image position. Once occlusion takes place, the respective appearance models are used, in combination with a depth factor representing the depth order of the occluded objects, to segment the resulting group blob into regions which are classified as representing one or other of the merged objects.

Programmable or user-defined visibility functions can be defined to achieve rendering effects and eliminate rendering errors. A renderer traverses the set of geometry samples potentially visible to an image sample. Rather than accumulate opacity and color in strict depth order, the renderer can invoke visibility functions associated with some or all of the geometry samples. Each geometry sample's visibility function can access attributes of any other geometry sample associated with the image sample. Furthermore, each geometry sample's visibility function can identify the position of its associated geometry sample and any other geometry samples in the depth sequence of geometry samples associated with an image sample. A visibility function can return any arbitrary value based on attributes of its associated geometry sample, attributes of other geometry samples associated with the image sample, and / or the position of geometry samples in the depth sequence associated with the image sample.
