It acts like living passwords for humans as its texture is stable throughout the human life. Watershed algorithm depends on ridges to perform a proper segmentation, a property that is often fulfilled in contour detection where the boundaries of the objects are expressed as ridges. The principle advantage that the retinex offers is that for different lighting conditions classifications derived from the retinex preprocessed images look remarkably 'similar', and thus more consistent, whereas classifications derived for the original images, without preprocessing, are much less similar.
