  Abstract

In order to reduce the complexity of HEVC, we propose a fast mode decision algorithm in depth videos. Since almost CU mode is decided as SKIP mode in depth-continuity regions, we design the algorithm using the property of depth videos. If cost of SKIP is smaller than the multiplication between the threshold for EarlySKIP and average cost of SKIP, EarlySKIP is performed, Otherwise, we calculate Inter 2N×2N. Then, if motion vector of Inter 2N×2N is 0 and variance of CU is smaller than threshold for inter, we skip Inter 2N×N, Inter N×2N. Experimental results show that our proposed algorithm reduces the encoding time from 39% to 82 % with negligible PSNR loss and bitrate increase.
