Video Coding using Separated Sign Coding and Motion Compensation

Abstract: Haar wavelet is the most important mathematical tool which has stimulated many developments, particularly in signal and image processing. The main advantage of Haar is the multi-resolution properties. The major challenge in this video coding is motion management using HWT. To reduce the cost of storage and the bandwidth transmission of video file, a new method is proposed in this paper. The new method is the sub-band coding approach that employs Haar Wavelet Transform (HWT) and is based on a separate sign coding (SSC) from wavelet coefficients amplitude. To avoid the problem created by the lack of invariance translation, we use the method motion compensation (MC) technique.Results shows that PSNR become good compared to other techniques.
