Abstract :
A new fast 3D wavelet transform based algorithm for video compression is presented. The main difference between it and the classical video compression algorithms is the temporal decomposition. The new algorithm reduces heavily the processing time for compression and decompression of video sequences, keeping or overcoming the quality of the reconstructed sequences. In addition, it cuts the memory demands heavily. Some figures show the experimental results
