Video Compression using Inter Color Prediction Scheme

摘要

In most of the video coding standards YCbCr color space is used as the input image format and most of the compression techniques are reducing redundancies in each Y, Cb, Cr component plane. In this paper we introduce new inter color prediction scheme that can further improve coding efficiency by exploiting the redundancy of chroma component within a sequence. Simulation results show that the proposed algorithm can lead up to 20% of average bit-rate reduction or equivalently 0.7dB quality improvement in chroma.
