| Abstract(in English) | In this research, we investigated the effect of image noise on perceived sharpness. To avoid the difficulty in characterizing natural image, we used as stimuli achromatic 2D sinusoidal grating and 2D uni-frequency pattern, which is one of the simplest forms of image, with various amounts of white Gaussian noise added. Then observers were asked to evaluate their sharpness. For 1D grating stimuli, sharpness seemed independent of noise amount, while, for 2D patterns, it increased with increasing noise. We think this is in line with the observation in our preceding research that sharpness increase by image noise is rather due to enhanced texture than due to enhanced edge. |
