An Algorithm of Adaptive Post-processing to Reduce the Block Artifacts in the Block-based Transform Image Coding Techniques
Ge Tang · 2002
In the block_based transform image coding techniques,especially in the video coding at very low bit rate,block artifacts influence the subjective quality seriously.In this paper we propose an adaptive post_processing algorithm to reduce the block artifacts,which has the property of low computational burden and obvious effect.Simulation results show that the proposed algorithm can improve the subjective quality and objective PSNR of the coded image.
