The problem of simulating the motion of evolving surfaces with junctions according to some curvature-dependent speed arises in a number of applications. By alternately diffusing and sharpening characteristic functions for each region, a variety of motions have been obtained which allow for topologic

✦ Synopsis
Diffusion generated motion has been used to generate a variety of interface motions. In this paper, we present a new shape recovery model with diffusion generated motion. The approach is based on alternately diffusing and sharpening the initial region to move the sharp interface toward the boundaries of the desired objects. The shapes are recovered by an anisotropic interface motion with a local image property dependent speed. Our algorithm is simple and easy to implement. It automatically captures topological changes and works for both 2D and 3D image data. Experimental results for synthetic and real images are presented.
