7-7 Memory texture and its sensibility effect

Abstract

It is known that preference of some photographs is improved by adding noise. We propose "Memory texture" as a reason for the improvement of preference by the noise addition. "Memory texture" is the texture reproduced when we imagine the object. We investigated differences between real texture and memory texture by subjective evaluation of images added noise. Except as to potato image, memory textures were always not smaller than the real texture. Preferred textures were very close to the short-term memory texture in most objects.
