Abstract
This paper presents a new method for enhancement of the visual quality of compressed video sequences. The algorithm detects the location of a block grid, reduces coding artifacts and enhances sharpness of image details using integrated filtering that ensures low implementation cost and high quality. The results of our experiments show the high efficiency of the proposed approach.
