Description

We are developing an objective evaluation method for the H.264/AVC codec images which is highly correlated with subjective evaluation by human observers. In our previous report, we proposed an S-CIELAB-based method with a spatial limitation in calculation for this purpose. We also presented that the objective evaluation values by the proposed method for the images at just noticeable compression rate are similar. In this paper, it is confirmed that the similarity is still maintained among an increased number of images. Next, for the images at several levels of degradation noticeable compression rates, the correlation between the subjective evaluation value and the objective evaluation values by the proposed method and other conventional methods were compared. As a result, the proposed method was superior to the other methods both in the evaluation at just noticeable compression rate and in the evaluation at degradation noticeable compression rates.<br>
