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.

There are many rendering techniques using point-based super-sampling. By the super-sampling, more sampling gets more quality. But how many samples do we need? We can only estimate this from statistics. In this research, we introduce a new concept Micro point. Using the Micro point, we get aliasing free images without super-sampling.

When synthesizing images with fine objects like hair, we usually use sub-pixel drawing techniques to improve image qualities. In this study, we demonstrate that it is possible to make images look finer by properly adding Gaussian noise.
