Abstract :
This paper presents a new method for equalizing colors of objects in two images of the same scene taken in different illumination conditions. The method outlined compensates for differences in colors by separately equalizing their achromatic and chromatic components. The equalization of the 1-D achromatic channel is carried out with a standard technique for gray-level images whereas the equalization of the 2-D chromatic channel is considered as a problem of image warping. The experiments reported show the effectiveness of our method
