A Fast Depth Determination Algorithm for High Efficiency Video Coding

In this paper, a fast depth partition algorithm for High Efficiency Video Coding (HEVC) is proposed. HEVC improves the coding efficiency by using large coding units while increases the coding complexity evidently. This paper analyzes the depth correlation between adjacent frames to fast determine the depth of current coding unit. The skip mode is also adopted for better performance. Experimental results show that our algorithm can reduce 52% coding complexity compared with original HEVC algorithm. Meanwhile, the average PSNR only decreases 0.09dB and the average coding rate is decreased about 0.58%.
