A NEW APPROACH FOR EVALUATING THE QUALITY OF DE-BLOCKED IMAGES

Ramesh Medaboyina, S. Srividya

Abstract


JPEG Compression is the most prevalent technique or method for images codecs. But it suffers from blocking artifacts. In this paper a comparison of the perceptual quality of deblocked images based on various quality assessments metric is done. A proposed PSNR including blocking effect factor was used instead of PSNR. Another quality assessment metric SSIM was used which produces results largely in accordance with PSNR-B. We show the simulation results, which prove PSNR-B produces objective judgments. The efficiency of deblocking algorithms were studied.
