| Abstract: |
This paper, aiming at the problem of the traditional RD rate control model and inaccurate bit allocation of multi-view high-efficiency video coding (MV-HEVC), proposes a rate control algorithm for MV-HEVC based on the similarity analysis of the views and timedomain complexity of the frame activity. First, the algorithm core uses the similarity analysis of the views to reasonably perform bit allocation among the views. Then, the frame layer and basic unit layer bit allocation and rate control are performed based on the frame rate, target buffer capacity, actual buffer size, and active time domain complexity of the frame. The experimental results show that compared with the fixed bit allocation algorithm applied to views, the proposed method not only effectively controls the bit rate of multiview video coding with a rate control accuracy of over 99% but also improves the PSNR by 0.38dB.
