In this article, we propose a new colour image segmentation algorithm by unsupervised classification of pixels. This procedure iteratively constructs the classes by histogram multithresholding. For this purpose, the procedure selects different colour spaces in which the pixels belonging to the modes of the 1D-histograms present remarkable connectedness properties, so that each mode corresponds effectively to a region in the image.
