Dipole and higher moments are physical quantities used to describe a charge distribution. In
analogy with electromagnetism, it is possible to define the dipole moments for a gray-scale
image, according to the single aspect of a gray-tone map. In this paper we define the color
dipole moments for color images. For color maps in fact, we have three aspects, the three
primary colors, to consider. Associating three color charges to each pixel, color dipole
moments can be easily defined and used for edge detection.
