| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In video coding using block transforms, blocking artifacts often occur in compressed images especially at low bit rates. Although PSNR and SSIM are often used as objective quality measures of compressed images, they cannot fully evaluate degradation of image quality affected by the blocking artifacts. In this paper, based on the results of a number of subjective evaluations collected for MPEG-2 compressed image sequences, we evaluate the correlation between image features and subjective evaluations of blocking artifacts. We also investigate an NR-type evaluation method of the blocking artifacts as an application of the above results. | |
