Complexity Reduction of HEVC SAO Intra Modes By Adjustment of Offset Values

Adjustment of Offset Value for Reduction of Complexity in HEVC Intra Mode

In this paper, we propose a complexity reduction method of sample adaptive offset (SAO), which is an in-loop filter in high-efficiency video coding (HEVC). In the conventional SAO, an offset value is calculated for each coding tree block (CTB) to minimize the error between the original and reconstructed images. In order to determine the optimal offset value, all offset candidates are examined a...

A pipelined VLSI architecture for Sample Adaptive Offset (SAO) filter and deblocking filter of HEVC

This paper present a high throughput design for Sample Adaptive offset (SAO) filter and deblocking filter used in an HEVC decoder. A five-stage pipelined architecture is proposed to support both SAO filter and deblocking filter on a 32 × 32 pixel block basis. Deblocking filter and SAO filter can work simultaneously in consecutive pipeline stages. The on-chip SRAM can also be shared by deblockin...

Low-Complexity Rate-Distortion Optimization Algorithms for HEVC Intra Prediction

HEVC achieves a better coding efficiency relative to prior standards, but also involves dramatically increased complexity. The complexity increase for intra prediction is especially intensive due to a highly flexible quad-tree coding structure and a large number of prediction modes. The encoder employs rate-distortion optimization (RDO) to select the optimal coding mode. And RDO takes a great p...
