For millimeter wave image having a lower resolution and a lot of noises,edges are partly lost to a certain extent or contaminated severely by noise.In this paper,a new edge-preserving self-snake model for the millimeter wave image de-noise is presented.The edge stopping function which is approximated to zero around fine structures and is close to one in the interior of homogeneous regions is constructed with the non-local gradient having maximum peak only at edges and good tolerance for noise.A discrete alg...
