A New Multiphase Image Segmentation Model by Piecewise Constant Level Set Method
Hung Bing · Microcomputer applications · 2008
This paper proposed a new multiphase image segmentation model based on the model of Yoon Mo Jung etc and the Mumford-Shah model with Piecewise Constant Level Set Method(PCLSM).The model output a single multiphase distribution from which each individual segment or phase can be easily extracted.The model can also have a good segment under a moderate amount of noise in the observation data.The steepest method is used to solve the total variation minimization problem.A function which is introduced to choose the values of parameters accelerates the algorithm's convergence rate.Numerical experiments show the new model's efficiency and it can deal accurately with images with T-junction.
