Efficient RGB Video Coding Using Adaptive Inter-Plane Residual Prediction

This paper presents an efficient video coding algorithm in the RGB color space. Currently most video coding algorithms are based on a decorrelated color space such as YCbCr which has reduced inter-color redundancy. For high fidelity video applications, however, it is essential to maintain the original signal fidelity. In pursuit of both high fidelity and coding efficiency, we propose an adaptive inter-plane residual prediction algorithm exploiting inter-color redundancy of the RGB signal. Simulation results show that the proposed algorithm can increase RGB video coding efficiency up to 0.9 dB, compared to the existing H.264/AVC High 4:4:4 Intra profile.
