Abstract
The establishment of an objective evaluation method highly correlated with the subjective evaluation is desired for picture quality evaluation. We have proposed an objective evaluation method considering human visual characteristic such as the contrast sensitivity function and the masking effect. However, the performance of the proposed method, S-CIELAB, still remained comparable to conventional quality measures. Thus, we improved the proposed method by modifying the computation of the masking effect. The modified method showed better performance than the conventional evaluation measures.
