In this paper, we propose a novel frame-level rate control algorithm for videos with complex scene in High Efficiency Video Coding(HEVC). To achieve a constant bitrate output and reduce the mismatch ratio of bitrate for time varying wireless links, the relationship of content complexity, QP and bitrate is utilized to adjust bit allocation for each GOP and frame via linear extrapolation. In addition,...
Rate-distortion optimization is widely used in modern video codecs to make various encoder decisions in order to optimize the trade-off between bit-rate and quality. The distortion models used in HEVC are mean squared error (MSE) and sum of absolute difference (SAD), both of which are not always reflective of perceptual quality. In this paper, we show that SSIM, which has been found to be a good indicator...
