| Abstract(in English) | In the field of image understanding and computer vision, it is important to estimate the scene illumination. Our previous paper, we proposed a method for estimating color temperature of the illuminant source from a color image acquired by a CCD camera. We assume that illumination is approximated by blackbody, and we used the correlation of sensor output. The present papers describes the algorithms for practical use and experimental results using an image database. We propose use of the reciprocal scale of color temperature, called "mired", in order to obtain perceptually uniform illuminant classification, rather than physical illuminant classification by the original color temperature scale. We examine the performance of our algorithm, and show an application to color correction. |
