20090110077 | IMAGE CODING DEVICE, IMAGE CODING METHOD, AND IMAGE CODING INTEGRATED CIRCUIT - When compression encoding processing of an image is performed in units of macroblocks using pipeline structure, application of the skip mode or the like according to MPEG4AVC to compression encode an encoding target block requires motion vectors and the like of adjacent blocks of the encoding target block. However, depending on the structure of the pipeline stages, the motion vectors and the like may not be determined. In such cases, the skip mode cannot be applied to compression encode the encoding target block. The present invention aims to solve this problem and (i) calculates all motion information candidates, of the encoding target block, corresponding to all motion information selectable by a previous block of the encoding target block, and (ii) selects, as the motion information of the encoding target block in the skip mode, the motion information corresponding to the motion information determined for the previous block. | 2009-04-30 |
20090110078 | TEMPORAL VIDEO FILTERING FOR REAL TIME COMMUNICATION SYTEMS - Background vs. foreground decisions for video frames to be compressed and transmitted in a real time video communication system are made based on a non-parametric approach using signs of pixel value changes in sequential frames. Pixel value changes are tracked as negative or positive. Cost functions may be assigned to rows and columns of predefined blocks and a decision made based on randomness of the signs within the block whether the block represents background (noise) or foreground. Recursive temporal filtering is then employed to reduce the background noise progressively resulting in increased compression and transmission efficiency. Offset tiling is used to increase accuracy of randomness determination when blocks include background and foreground combinations. | 2009-04-30 |
