Combining prior shape and Mumford-Shah model for active contour segmentation
Zhongke Wang · Computer Engineering and Applications Journal · 2011
The active contour segmentation based on prior shape and M-S model has been widely used in image segmentation because of their computational efficiency and stability.Based on level set method,the novel model using the active contour model,prior shape and Mumford-Shah model can control evolvement of curve.Prior knowledge on certain object is a useful guidance in image segmentation.It exploits the prior knowledge of desired object’s shape through a Principle Component Analysis(PCA) method.By numerical experiments presented in the paper,the proposed approach is robust to cluttered background,partial occlusions,missing and noise with the specific shape.
