专利汇可以提供VIDEO CODING METHOD USING A BLOCK MATCHING PROCESS专利检索,专利查询,专利分析的服务。并且The invention relates to the field of two-dimensional sub-band coding techniques, extended to video data by including the temporal domain within the decomposition using motion estimation and compensation. The invention relates to a method allowing to keep the amount of motion vector information reasonably low and to allocate more bits to texture in non-moving areas. Said method first performs a preliminary analysis which allows to identify parts of the image not requiring a precise description of the motion information, followed by a motion estimation on the basis of this preliminary information. A decision based on the energy of the high frequency temporally filtered sub-bands is then taken, before the final motion compensation operation, in view of the selection of the most appropriate motion vector.,下面是VIDEO CODING METHOD USING A BLOCK MATCHING PROCESS专利的具体信息内容。
