摘要： A video image sequence is coded or decoded. By motion compensated temporal filtering, using discrete wavelet decomposition, the discrete wavelet is decomposed by dividing the video image sequence into source and destination groups of images. An image in the destination group is determined from at least one image including pixels in the first group of the source group. The representative image includes pixels and subpixels determined from pixels and subpixels obtained by upsampling at least one image in the source group.
