Summary:
In this paper, a CU size early determination algorithm is proposed to efficiently reduce complexity for the hardware implementation of HEVC inter coding.The proposed algorithm can be positioned as a pre-processing for the rate-distortion optimization (RDO) which can decide the CU size by only analyzing the original pixels based on the characteristics analysis of the coding unit using sobel-filter.Simulation results show that the proposed algorithm will induce PSNR loss 0.042dB with only 1.72% bitrate increase, compared to HM9.1.
