摘要

This paper presents an efficient rate control algorithm based on our content-adaptive initial quantization parameter setting scheme for H.264/AVC. For versatile video scenes, our algorithm can adaptively set an appropriate initial QP based on the textural complexity estimated from the first picture. In addition, our bitallocation strategy effectively distributes the bit-rate budget based on the monotonic property to enhance the coding efficiency. Our proposed algorithm surpasses JVT-H014 rate control algorithm and Cauchy-density-based bit-allocation scheme in terms of average PSNR for about 0.47 dB and 0.81 dB respectively. Besides, our algorithm provides more impressive visual quality and more robust buffer controllability.
