20120207217 | VIDEO CODING BASED ON GLOBAL MOVEMENT COMPENSATION - A method for video coding of at least one digital picture sequence is disclosed. The pictures of said sequence can be intermediary pictures or key pictures used as references for the coding by motion compensation of intermediary pictures. The intermediary pictures are coded per area based on a global motion compensation GMC in the forward and backward direction from key pictures, the areas of the intermediary picture being constituted either by merging of global motion compensated key picture areas, or by conventional coding, the choice between merging and conventional coding being made according to the result of a measurement of coherency between the signals of global motion compensated key picture areas. A video coding device and a video decoding device are also disclosed. | 08-16-2012 |
20120250764 | PROCESS FOR CODING VIDEO DATA OF A SEQUENCE OF IMAGES - The process comprising splitting of an image into blocks, intra coding of a current block using spatial prediction based on a matching pursuit algorithm selecting, from a dictionary of atoms, the atom the most correlated with a causal neighborhood of the current block, is characterized in that it performs the following steps: determination of the two dimensional shift between the causal neighborhood and the selected atom, generation of at least, a new phased atom taking into account the values of the two dimensional spatial shift, use of this new atom for intra prediction, according to the matching pursuit algorithm, if better correlated than the selected one. Application to video data compression. | 10-04-2012 |
