Dipole and Quadrupole Moments for Edge Detection

Dipole and Quadrupole Moments for Edge Detection

Amelia Carolina Sparavigna

Dipole and higher moments are physical quantities used for describing the charge distribution. In analogy with electromagnetism, it is possible to define the dipole and quadrupole moments for a gray-scale or color image, according to the single aspect of a graytone or color map. In the papers

I define the dipole and quadrupole moments for color images and show how they can be used for edge detection and other applications.
