In order to carry out multi-phase image hierarchical segmentation,a Chan-Vese model was adopted serially to segment an image into two subregions including object and background regions.When any of the resulting subregions require additional segmentation,apply Chan-Vese model to those subregions again until all objects in the image are segmented.This method is simpler than Mumford-Shah model,and it is accurate for object location.Each segmentation step can get significant regions.The experimental results sho...
