Extended active contours model without edges
Chuanjiang He · Computer Engineering and Applications Journal · 2009
Intensity changes are crucial for accurate segmentation of many images.However,intensity changes are ignored in active contours model without edges (called CV model,usually),one of the most popular region-based active contour models.This paper proposes an extended version of CV model,which is able to utilize intensity change information in images.The experimental results show:(1)the Extended CV(ECV) model can be used to segment certain types of images to which CV model is not applicable. (2)ECV model is also able to segment the images that CV model is applicable to,and is significantly fewer sensitive to noise than CV model.
