Web14 de set. de 2005 · Abstract: In 3D subband coding, motion-compensated temporal filtering (MCTF) technique, especially with the adaptive 5/3 wavelet kernel, efficiently exploits the temporal correlation among neighboring pictures. It can be achieved alternatively by the hierarchical B picture coding technique with the same decomposition as the temporal … WebThe hierarchical B GOP structure includes a plurality of B pictures between an I picture and a P picture or between two P pictures. The multiple B-pictures are organized in a hierarchical structure. For example, for a hierarchical B GOP with a GOP length of 8, the GOP may consist of I 0, b 1, B 2, b 3, B 4, b 5, B 6, b 7, P 8,.
