+HSV Formats

+These formats store the color information of the image
+in a geometrical representation. The colors are mapped into a
+cylinder, where the angle is the HUE, the height is the VALUE
+and the distance to the center is the SATURATION. This is a very
+useful format for image segmentation algorithms.
