Abstract

This work lies within the scope of color image segmen- tation by pixel classification. Classes of pixels are gener- ally constructed by mode detection applied to the color his- togram, but this method tends to fail when the color distri- butions of the different objects highly overlap in the color space. A new characteristic function of the distribution of the colors within the image is proposed here. The compaci- gram takes into account both the distribution of colors in the color space and the spatial location of colors in the image plane. Experimental tests on two reference images show that the mode detection technique based on a convex- ity analysis of the compacigram leads to promising results for segmentation purposes.
