| Abstract(in English) | In the food image acquired by a digital camera, its lightness and saturation components are sometimes decreased depending on the illumination environment. In this case, the food image does not seem to be delicious. In general, RGB components are transformed into lightness, saturation and hue components, and then the lightness and saturation components are enhanced so that the food image seems to be delicious. However, these processes are complex and involve a gamut problem. In this report, we propose the lightness and saturation enhancement method in RGB color space for the food image. In this method, at first, the lightness components are enhanced avoiding the saturation deterioration. Then the saturation components of the regions having the hue components frequently appeared in the foods are enhanced. In this study, to illustrate the effectiveness of the proposed method, the enhancement experiments using various food images are done. |
