Abstract :
The widespread of video based applications in nowadays life has increased the need of video coding scalability. In fact, spatial scalability allows the adaptation of the bit-stream to end users as well as varying terminal capabilities and network conditions. In this context, many Discrete Wavelet Transform (DWT) based video codec are proposed. We can sort out that the well known integer to integer DWT such as 5/3 and 9/7-M filters do not perform well in coding the residual frames of the video in terms of PSNR.
