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on the span and being maintained in depth order (590) and subject to removal of depths where the corresponding depth is no longer active.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 color in the run are reduced to a single equivalent color (6115, 6116, 6117) having an associated accumulated contribution. Many other developments are disclosed.

A method of rendering a scan line of a graphic object image in a scan line renderer for spans of pixels laying between consecutive x-ordered edges intersecting the scan line includes maintaining a set of depths present in the rendering of the scan line, with the set being maintained in depth order. For each span, the set contains at least those depths that are active in the span, and the set is subject to removal of at least one depth at a subsequent span on the scan line where the corresponding depth is no longer active.

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.

A system that renders a three-dimensional model which contains semi-transparent surfaces. During operation, the system renders the semi-transparent surfaces in the three-dimensional model by performing the following operations iteratively for each semi-transparent surface in draw-order instead of depth-order: (1) rendering the semi-transparent surface to a Z buffer, (2) calculating a cumulative transparency value for each pixel of the semi transparent surface as a function of the transparency value for each opaque and semi-transparent surface that intersects the pixel and is in front of the Z-value for the pixel in the Z-buffer, (3) attenuating a surface color value for each pixel in the semi-transparent surface by the cumulative transparency value for the pixel, and (4) adding the attenuated surface color value to a corresponding pixel value in the image buffer.

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.

The invention relates to the technical field of civilian defense and camouflage and discloses a civilian defense digital camouflage net and method. The camouflage net is composed of multiple different camouflage net units and annular ropes. A large net is formed by weaving and connecting the different camouflage nets through the annular rope arranged on the periphery of each camouflage net unit. Each camouflage net unit is composed of a bottom net and a net face. Each net face is made of cut-flower composite base cloth which prevents infrared rays and radar and has a color system of shallow gray, deep gray, jade green, brown and soil color, wherein the color system imitates a background. The civilian defense digital camouflage net can be rapidly assembled according to on-spot backgrounds and seasons, civilian defense primary objectives are merged with the surrounding backgrounds and survival capability of the objectives is improved. Based on the relevant principle of blocking a perception depth order in visuality, square corners and adjacent spots are used for blocking so that observers have an illusion that distances from the spots are different and spatial layering feelings are generated. Boundaries of the digital camouflage spots are not clear and the camouflage net has smooth continuous curves which are not easy to identify by the eyes.
