Abstract

A number of lifting-based video coding schemes have been recently proposed for scalable video coding. We present a novel multi-view image codec based on a wavelet lifting scheme. The proposed lifting scheme with disparity compensated channel filtering is very efficient in terms of compression performance, memory requirements and implementation. We propose a number of enhancements to the basic scheme, such as hybrid prediction, adaptive weighing in update step and overlapped block disparity compensation which yield significant improvements in rate distortion performance. Experimental results show image quality gains of up to 1.5 dB and 1.2 dB against well established methods such as block-matching Haar and 5/3 wavelet lifting respectively.
