摘要： The generation of images is done by the computation of the motion vectors representing the evolution from one image 2D to the other, directly from the co-ordinates and coefficients of geometrical transformation, of associated points in the 3D scene. The applications relate to the generation of monocular sequences by temporal interpolation and of stereoscopic sequences by extrapolation.

摘要： A method of generation of computer images of a three-dimensional scene constituted by a set of facets, viewed from a point of observation along a viewing axis. The facets are projected on the surface of a sphere whose center is the point of observation of the scene and wherein the surface of the sphere is divided in a special way into elementary surfaces, each corresponding to a pixel on the spherical surface, in such a manner that the orthogonal projections of the elementary surfaces on a reference plane passing through the point of observation and perpendicular to the viewing axis of the scene all have same value. An application is the generation of visibility or distance images. Another application is radiosity.

摘要： The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

摘要： Method of mapping source colors from a source color device having an actual source gamut that is represented by a source convex (gamut boundary descriptor) and a source non-convex into target colors for a target color device having an actual target gamut that is represented by a target convex and a target non-convex, comprising, 1—if the source color to map is located outside the source non-convex, a pre-mapping step that maps the source color into the source non-convex, 2—if the mapped target color is located outside the target non-convex, a post-mapping step that maps the target color into the target non-convex. This method allows precise gamut mapping while allowing also for simple geometrical operations using convex gamuts.

摘要： Preferably, seven classes of observers are defined, according to different sets of Color Matching Functions. By displaying specific color patches of a classification chart using color display devices having different sets of primaries, and by asking an actual observer to compare his perception of the same color as displayed on each color display device, the method allows assigning said observer his specific class. It is proposed a specific apparatus to implement this method.

摘要： Before the transmission of the source color values of the images of each group Gk of images of this sequence, a partial color transform LUT related to this group Gk is generated, then transmitted, —and, a resultant color transform LUT related to said group Gk is reconstructed by combining the transmitted partial color transform look up table of this group Gk with, if any, all the other partial color transform look up tables that have been previously transmitted, —then each images of said group are color transformed using this LUT. The invention allows a good precision of color transformation with a limited bandwidth.
