An algorithm of asteroid craters detection based on Gradient Vector Flow Snake model

Abstract

A method of craters detection based on Gradient Vector Flow (GVF) and Snake model is presented in this paper. Firstly, the original edge map of craters is detected by Canny operator, and the concave boundaries and ruptures are allowed in the edge map. Then, the external force of, which is called GVF, is computed as a diffusion of gradient vectors of the… (More)
