Abstract(in English) | An objective evaluation measure AWSNR (Advanced Weighted Signal to Noise Ratio) which compensates coding noise by considering entropy in every 16×16 pixels sub-block is proposed. In order to clarify the relationship between MOS (Mean Opinion Score), SNR and entropy, a subjective evaluation test using twelve kinds of textures with ten different noise level is carried out. After the noise compensation factor is experimentally derived from the entropy-SNR characteristics when MOS=4, 342 images with five kinds of coding noise or with random noise are evaluated subjectively and objectively. The result shows an improved correlation coefficient with the MOS-AWSNR of 0.83, compared to 0.64 with the MOS-SNR. |
