专利汇可以提供METHOD OF ENCODING A SEQUENCE OF FRAMES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 filtering step applied to the frames considered as a 3D volume. The decomposition is applied to successive groups of frames after motion estimation and compensation which lead to double-connected pixels corresponding to uncovered regions. A minimization criterion is provided for choosing in the current frame, for the temporal filtering of a double-connected pixel of the reference frame, the pixel that leads to a minimum energy of the detail subband. The temporal part of the 3D decomposition may be a temporal wavelet transform that includes a temporal filtering based on the lifting scheme, including an overlapped motion compensation using, in the prediction step of said scheme, an average of pixels from adjacent windows in the reference frame.,下面是METHOD OF ENCODING A SEQUENCE OF FRAMES专利的具体信息内容。
