Abstract

This chapter deals with the video encoding techniques using Spatial and Temporal Discrete Wavelet transform (DWT). It discusses about two video encoding mechanisms and their performance at different levels of DWT. Memory is the major criteria for any video processing algorithm, so in this chapter focus on the efficient utilization of the system memory at increased level of spatial and temporal DWT is presented. Out of these two mechanisms, one of the mechanism implements multi resolution analysis in temporal axis. Here the chapter also discuss about implementing the different DWT level in spatial and temporal domain. In this chapter, the Haar wavelet is taken as the reference. Finally, the compression of the videos is achieved by using the standard embedded zero wavelet tree (EZW) mechanism. The performance of the EZW based compression in terms of the PSNR and compression ratio is shown for various videos in this chapter.
