A New Video Coding Based on 3d Wavelet Transform and Motion Compensation

Abstract

In this paper, the classical algorithm of 3D wavelet transform is improved and a new video coding based on the improved algorithm and motion compensation is proposed. The main difference between the classical algorithm and the new algorithm is the temporal decomposition by wavelet transform. With the new algorithm, video sequence is firstly separated into two groups according to the parity of each frame. Then the improved algorithm for temporal decomposition is applied to each group separately which resulting several high frequency frames and one low frequency frame in each group. After that, the motion compensation is only performed in the two low frequency frames in order to eliminate the interframe redundancies. Experiments results show that the proposed scheme has better coding performance compared with other schemes based on 3D-VVT.

A New Video Coding Based on 3D Wavelet Transform

“…In [9], a new video coding based on 3D-WT and hierarchical 3D zerotree hybrid is discussed. An improved SPIHT algorithm is proposed in [10] and a new coding based on 3D-WT and motion compensation is presented in [11].
