Colour correction pre-processing and chrominance reconstruction post-processing for multi-view video coding

Abstract

In a multi-view video system, a great amount of data for storage and transmission raise an inevitable problem to be solved. In this study, a new multi-view video coding (MVC) method is proposed by performing colour correction as a pre-processing step and chrominance reconstruction as a post-processing step. In the proposed method, colour correction is first performed to eliminate colour differences among views and to improve coding efficiency simultaneously. Then, chrominance information in some particular views is discarded to reduce bit-rates. Finally, the discarded chrominance information is reconstructed accurately at the decoder. Experimental results show that the proposed method can better increase the bit-rate saving than the original MVC system. Moreover, the proposed method can accomplish higher quality reconstruction at the trivial cost of quality degradation.
