A method and apparatus estimates the strength of block artifacts in compressed video is described. Block artifacts are associated with the block-based image/video compression schemes. The block artifacts deteriorate the quality of compressed image and video, especially at low bit rates. A deblocking method measures the strength of the block artifacts at each block boundary and adjusts the deblocking parameters accordingly to improve the performance of the overall deblocking process. A method and device to measure the strength of block artifacts based on the global and local edge information of the current picture is provided.
