| Abstract | In this paper we introduce a block-classified bidirectional motion compensation scheme for our previously developed wavelet-based video codec [24,25], where multiresolution motion estimation is performed in the wavelet domain. The frame classification structure described in this paper is similar to that used in the MPEG standard. Specifically, the I-frames are intraframe coded, the P-frames are interpolated from a previous Ior a P-frame, and the Bframes are bidirectional interpolated frames. We apply this frame classification structure to the wavelet domain with variable block sizes and multiresolution representation. W-e use a symmetric bidirectional scheme for the B-frames a n d classify the motion blocks as intraframe, compensated either from the preceeding or the following frame, or bidirectional [Le., compensated based on which type yields the minimum energy). |
