摘要： Accuracy and efficiency of video quality measurement are major problems to be solved. According to the invention, a method (506) for accurately predicting video quality uses a rational function of the quantization parameter QP, which is corrected by a correction function that depends on content unpredictability CU. Exemplarily, the correction function is a power function of the CU. Both QP and CU can be computed (511) from the video elementary stream, without full decoding the video. This ensures high efficiency.

摘要： A method and a system for crowd simulation are described. Interactions between the agents in a crowd and the terrain the crowd passes through are taken into account in the present invention for simulation. Agent attributes and terrain attributes are employed to define the reaction of the agent to the terrain and to other neighboring agents, and the reaction of the terrain to the agent, respectively. Steering forces incorporating the agent and terrain attributes are calculated and applied to the corresponding agent. The position change for each agent is thus the combined results of the interaction among the agent, its neighboring agents and the terrain underfoot.

摘要： Methods and apparatus for artifact detection are provided by the present principles that measure the level of artifacts, such as those caused by temporal concealment of errors due to packet loss, for conditional error concealment. The principles are based on an assumption that sharp edges of video are rarely aligned with macroblock boundaries so video discontinuities are checked throughout the video. The scheme solves the problem of error propagation when temporal concealment of artifacts is used and the high false alarm rates of prior methods. Artifact detection methods are provided for regions of an image, an entire image, or for a video sequence, with error concealment provided conditionally based on the artifact levels.

摘要： In 3D mesh coding, the geometry data is compressed by spatial tree based approaches. Bitstreams that result from the traversal of a tree structure of spatial tree based approaches for encoding 3D mesh models have systematically special redundancies, which is exploited for further improving the mesh model compression. A method for encoding a bitstream comprises steps of defining (51) at least a first and a second symbol group of binary symbols, with S1 being a subset of S2, determining (52) within the bitstream first portions (J1,J2), second portions (K1) and third portions (N1,N2,N3), wherein first portions have Th1 or more consecutive S1 symbols and second portions have Th2 or more consecutive S2 symbols, encoding (54) the bitstream, wherein first portions, second portions and third portions are encoded (54A,54B,54C) using different codes, and encoding (55) values (C 1 ) indicating the boundary positions between the first, second and third portions in the bitstream.
