| Summary: | Traditional block-based video coders suffered from annoying blocking artifacts in low bit-rate coding.Aiming to high complexity for determining the block edge strength of deblocking filter,a fast in-loop deblocking filter based on content pre-analysis was proposed,which utilized STGS-image to partition character of different regions and measured the block effect intension in blockwise based on optical flow equation and relativity of interframe.Experimental results show that the proposed greatly reduces the complexity of filter algorithm,and then the subjective image quality of the proposed is approximate to that of the H.264 in-loop filter. |
