A novel method of Post processing algorithms for image and VP8 video codec's

Abstract

This paper proposes post processing algorithm by employing modified adaptive (method or technique) in loop deblocking filter for VP8 and Image codec's, mainly because blocking artifact is one of the most annoying artifact especially in video and image compression coding. The method proposed improves the quality of the reconstructed image and as well as video. In this paper, we have introduced deblocking algorithm, classified them into several categories and implemented on Image and Video codec's. On the other side the PSNR is widely used for checking the quality of the compressed image and video. However, PSNR sometimes does not reveal the quality perceived by human visual system. In this paper, we will introduce another measurement to estimate the blockiness in the compressed image and video. So that VP8 video codec and image codec is successfully implemented based on this method to achieve better visual quality of video data and also achieve good performance.
