抄録

An objective evaluation measure AWSNR that reflects human visual characteristics is proposed. In the measure, the spatial complexity of the original picture is determined from the fractal dimension, and the human visual sensitivity to the brightness of the picture is considered. Furthermore, subjective observation areas are predicted based on local complexity, local brightness, and the human spatial frequency characteristics. From experimental results using 350 pictures evaluated by 30 testers, it was found that the correlation coefficient between the MOS (Mean Opinion Score) and the proposed AWSNR became 0.91.
