Blocking artifacts reduction for highly compressed frames with adaptive threshold

Video compression is the wide spread field in communication engineering and computer science that deals with illustration of video data, for storage and/or transmission. Block based motion estimation and motion compensation technique is widely used in most of video coding standards including H.264/AVC (Advance Video Coding) to compress raw video. Motion compensated block is transform coded and quantize before entropy coding to achieve high coding efficiency. But all block base operations introduces annoying blocking artifacts and degrade the quality of reconstructed video. In order to improve the quality of the reconstructed video, several deblocking algorithms have been proposed. This paper applies offset and shift algorithm to motion compensated frames and propose method of computing adaptive threshold based on movement associated with moving sequence. Experimental results indicate that algorithm outperforms with motion adaptive threshold in comparison of fixed threshold for highly compressed standard test images and video sequences.
