英文摘要	The emerging high efficiency video coding standard (HEVC) achieves significantly better coding efficiency than all existing video coding standards. The quad tree structured coding unit (CU) is adopted in HEVC to improve the compression efficiency, but this causes a very high computational complexity because it exhausts all the combinations of the prediction unit (PU) and transform unit (TU) in every CU attempt. In order to alleviate the computational burden in HEVC intra coding, a fast CU depth decision algorithm is proposed in this paper. The CU texture complexity and the correlation between the current CU and neighbouring CUs are adaptively taken into consideration for the decision of the CU split and the CU depth search range. Experimental results show that the proposed scheme provides 39.3% encoder time savings on average compared to the default encoding scheme in HM-RExt-13.0 with only 0.6% BDBR penalty in coding performance. ? 2014 IEEE.. ? 2014 IEEE.; EI; 0
