This paper deals with a hierarchical description of grayscale images based on image dipoles. An image dipole is a region whose lines of slope emanate from the maximum, and reach the same minimum. Incorporating an image dipole based representation of an image into a scale-space filtering, we proposed here a hierarchical image dipole description of the image. The proposed description consists of image dipole networks of selected scales, and linking of image dipoles across the scales such that it contains all transformations of the image dipole network in the scale-space.
