Reference frame selection in a hardware-based HEVC encoder

The multiple-reference-frame motion estimation (ME) is one of the features to improve the compression efficiency. However, the computational complexity for prediction increases in proportion to the number of reference frames. This paper proposes the reference frame selection algorithm for a hardware-based HEVC encoder. The integer-ME explores multiple reference frames to find the best one and t...

Implementation of fast HEVC encoder based on SIMD and data-level parallelism

This paper presents several optimization algorithms for a High Efficiency Video Coding (HEVC) encoder based on single instruction multiple data (SIMD) operations and data-level parallelism. Based on the analysis of the computational complexity of HEVC encoder, we found that interpolation filter, cost function, and transform take around 68% of the total computation, on average. In this paper, se...

Fast Coding Unit Decision Algorithm for HEVC Intra Coding

—High Efficiency Video Coding (HEVC) exploits quad-tree structured Coding Unit (CU) to improve compression efficiency. It saves about 50% coding bits as compared with the former standard H.264/AVC high profile. However, the computational complexity is dramatically increased for more partition blocks and coding modes supported in HEVC. In this paper, a fast CU decision algorithm is proposed to ...
