In this thesis, a new effective method for ringing artifact removal in compressed
images is proposed. Blocks with ringing artifacts are accurately
detected by our ringing artifact detection scheme. Range .filter is applied
to the detected block to remove ringing artifact. Simulation results demonstrate
that the proposed algorithm effectively reduces ringing artifact and
preserves image details as well. It also improves both visual quality and
PSNR of compressed images compared to existing approaches.
