Empirical study of morphological operators in color image enhancement

The use of mathematical morphology in low and mid-level image processing and computer vision applications has allowed the development of a class of techniques for analyzing shape information in monochromatic images. In this paper, we extend some of these techniques to color images. We have investigated the application of various methods for 'color morphology'. We present results of our empirical study for three different applications: noise suppression, multiscale smoothing, and edge detection.
