Paper Abstract

A new method for image sequence coding involving a wavelet packets transform is proposed to compact the energy of the transformed signal while preserving acceptable restitution quality. Based on an interframe coding scheme, the sequence is split into groups of frames where a similarity between successive frames exists. The best basis is generated for the first intra-frame, the first inter-predicted frame and the first inter-interpolated frame of each group and conserved for the following corresponding frames to reduce the computational complexity. Two different methods for on-line selection of the best basis are presented. The choice of the proposed technique is validated by experimental results where a codec based on motion compensated wavelet packets transform is presented.
