一种低复杂度的HEVC去方块滤波框架设计

HEVC is the latest video codec international standard. In block-based video coding, the resulting reconstructed image will have blocking artifacts, while HEVC is still a block-based video coding, and thus continues the in-loop deblocking filter. HEVC's deblocking filter module uses adaptive filtering to facilitate parallel processing, but computational complexity is still high. This paper introduces and analyzes the implementation of HEVC's deblocking filter, and points out the drawbacks of the current HEVC deblocking filter framework, and proposes a low-complexity framework of deblocking filtering. Experimental results show that the low complexity of the proposed block filter framework can effectively reduce the filtering time in the case of lossless image quality.
