Wenjuan Zhang · Dianzi Ke-ji Daxue xuebao · 2013
A general equivalent model is introduced based on the convex relaxation model of a class of vector-valued minimization problems.The presented model can be solved by split-Bregman algorithm.The computational efficiency is greatly improved.The method is applied to the Vese-Chan multi-phase segmentation model and Mumford-Shah model.Numerical experiments show our method has fast computing speed and good segmentation results,and is robust to the initial condition.
