Feeling Impression and Quantities Accompanying Calculation of Fluctuation in Color Image

Abstract

This paper proposes a set of three kinds of parameters as an indicator of human affective impression for color image, which can be obtained accompanying calculation of fluctuation such as 1/f fluctuation from power spectrum on the image's spatial frequency domain. Also this paper analyzes a relation between those parameters and feeling impression by changing those parameters' values. And we describe the results of the following two kinds of investigations. (1) Investigation of direct relation between the parameter values of natural images and human impression using the questionnaire survey 1. (2) Investigation as to how good affective impression the change of those parameters' values cause on human being, using questionnaire survey 2. From these results, we show that we can develop a sophisticated color image arrangement processing utilizing those three kinds of parameters.
