VIDEO ENCODING AND DECODING METHOD
专利汇可以提供VIDEO ENCODING AND DECODING METHOD专利检索，专利查询，专利分析的服务。并且The invention relates to a method for encoding a sequence of frames by means of a three-dimensional (3D) subband decomposition involving a spatial and temporal filtering step. Said decomposition is applied to successive groups of frames only after the implementation, on said frames, of motion estimation and compensation operations in the low temporal subbands at each level of the temporal decomposition. A motion compensated temporal filtering step between a previous reference frame A and a current frame B comprises in a first time a computation sub-step of the high frequency subband, followed by a computation sub-step of the low frequency subband. This filtering step is followed by an identification step of regions uncovered during motion, as being related to double-connected pixels, and this identification step is itself followed by a decision step, provided for choosing in the current frame, for the temporal filtering of a double-connected pixel of the reference frame, the corresponding pixel that leads to a minimum energy of the detail subband. The invention also relates to the corresponding decoding method.，下面是VIDEO ENCODING AND DECODING METHOD专利的具体信息内容。
