| Abstract(in English) | It has been shown that the sharpness evaluation method based on the cooperative human vision model is superior in performance to conventional methods and their improved methods reformulated so as to reproduce fundamental characteristics on sharpness in the same way as the vision-model-based method. These results imply that the vision-model-based method's high performance can be caused by its image observing mechanism. In order to clarify the effectiveness of the vision-model-based method and the influence of the image observing mechanism on performance more definitely, we apply the both methods to sharpness evaluation for edge-enhanced images and compare these two performances. Consequently, for edge-enhanced images, the vision-model-based method was superior in performance to the improved methods under almost all the evaluation conditions. This result suggests that the image observing mechanism in human vision can also play an important role in image quality evaluation. |
