Abstract

We present a graph-based approach to the production of hierarchical segmentations of grey- level images. The technique is designed to be as responsive as possible to the structure of the image but general in the sense that it is independent of the exact edge measure used. We present results using a novel edge measure which combines the first and second derivatives of the image to calculate the phase of the image with respect to scale. We combine this with the gradient to produce a value which reflects both the strength and the stability of candidate edges.
