        **Colorizes a 2-D label map for visualization using greedy coloring.**

        Label maps are produced by segmentation and other image analysis steps.
        Direct inspection of label maps can be difficult,
        because labels usually correspond to gray values which are difficult to
        distinguish visually from each other and from the image background.
        To facilitate the visual inspection of label maps, this tools converts
        label maps to color images, by assigning each label a unique color.
