A Mesh-Based Method for Wavelet Video Coding Using Edge-Detection in Low Frequency Subband

Abstract

In this paper, we propose a mesh-based method for motion estimation and compensation over low frequency subband for wavelet video coding. We concentrate on edge-detection information and apply different parameters using edge magnitude and edge angle values to indicate curvature values for objects. This helps to detect motion patches between adjacent frames for meshes. We analyze and compare coding efficiency with a variety of video test sequences. Experimental results show that our mesh method improves coding performance for videos with less globally distributed motions compared to local motions.
