| Abstract(in English) | In a food image acquired by a digital camera, its intensity and saturation components are sometimes decreased depending on the illumination environment. In this report, saturation and lightness enhancement method considering perceived lightness for food images is proposed. In this method, at first, the lightness components are enhanced in a range of preserved saturation. Secondly, the saturation components are enhanced keeping perceived lightness. Then it is enhanced only the regions of the food color. The parameter of the saturation enhancement is calculated so that the saturation of the low saturation pixels are not enhanced excessively. In this study, to illustrate the effectiveness of the proposed method, the enhancement experiments using various food images are done. |
