摘要: The goal of this paper is to develop a multiphase image segmentation method based on fuzzy region competition. A new variational functional with constraints proposed by introducing membership functions which represent several different regions in an image. existence minimizer established. We propose three methods for handling the minimization. also add auxiliary variables approximate such that Chambolle's fast dual projection can be used. An alternate minimization employed find solution, parameters and have closed form solutions. Numerical examples using grayscale color images are given demonstrate effectiveness methods.
