Analysis of Key Assessment Word for Extra High Quality Images

摘要

The coming information society will require images at the high end of the quality range. An all encompassing goal of our research is to develop Extra High Quality Imaging System which is able to convey the high level artistic impression faithfully. We define the high order sensation as such a high level artistic impression, and we consider that the high order sensation is evoked from the combination of the psychological factors which can be expressed by assessment words. In order to investigate the quality factors that are important for the reproduction of the high order sensation, we focus on the image quality evaluation for the extra high quality images using the assessment words of the high order sensation. In this paper, we have collected the assessment words relevant to the representation of the high order sensation, and we have obtained the key assessment word "image depth" based on the hierarchical structure between the representative assessment words. The experimental results have shown tha the key assessment word "image depth" has been able to evaluate the image quality of the extra high quality images quasi-quantitatively.
