Abstract EN
The joint collaborative team on video coding (JCT-VC) is developing the next-generation video coding standard which is called high efficiency video coding (HEVC).
In the HEVC, there are three units in block structure: coding unit (CU), prediction unit (PU), and transform unit (TU).
The CU is the basic unit of region splitting like macroblock (MB).
Each CU performs recursive splitting into four blocks with equal size, starting from the tree block.
In this paper, we propose a fast CU depth decision algorithm for HEVC technology to reduce its computational complexity.
In 2N×2N PU, the proposed method compares the rate-distortion (RD) cost and determines the depth using the compared information.
Moreover, in order to speed up the encoding time, the efficient merge SKIP detection method is developed additionally based on the contextual mode information of neighboring CUs.
Experimental result shows that the proposed algorithm achieves the average time-saving factor of 44.84% in the random access (RA) at Main profile configuration with the HEVC test model (HM) 10.0 reference software.
Compared to HM 10.0 encoder, a small BD-bitrate loss of 0.17% is also observed without significant loss of image quality.
