Abstract

Yim and Bovik proposed a referenced quality assessment method named PSNR-B. Base on PSNR, PSNR-B introduced a blocking effect factor (BEF) to measure the blocking effects of the test images, which is more effective for assessing the quality of deblocked images than PSNR. However, PSNR-B ignores the probable blocking artifacts of reference images, and disallows interchange of the test image and the reference. On these aspects, we find PSNR outperforms PSNR-B on assessing the quality of the test images. This paper aims at improving PSNR-B to a generalized metric system for compressed images. We present an improved quality assessment method of blocking artifacts for compressed images. A blocking effect ratio (BER) factor is proposed to evaluate the differences of blocking effects in both the test and the reference images. The proposed method integrates the merits of PSNR and PSNR-B, and Simulations prove the better performances.
