Abstract: In the field of image processing, it is well known that the gray level transform by Histogram Equalization (HE) for gray scale image effectively enhances the intensity contrast, in general. For the case of color image, the HE processing can be regarded as an elastic transform on the lightness axis in the RGB attribute space of input color image. In this paper, from the expansion of this idea, we propose some elastic transforms based on the HE on Principal Component axis, as arrangement processing for color image that can bring about impressive feeling effects. Moreover, we show the questionnaire survey on the results of the arrangement processing, and discuss the effectiveness in feeling impression.
