Edge-based active contour model with adaptive varying stopping function
结合自适应变化停止函数的边缘活动轮廓模型*

The edge stopping function is influence the results in edge-based active contour models. It is a strictly monotonically decreasing positive function only about the gradient magnitude of image. The active contour models based on this type of edge stopping function have the drawbacks of high sensitiveness to noise and inaccurately locating the edge of the images with intensity inhomogeneity. This paper proposed a new adaptive varying stopping function to hopefully overcome the two drawbacks above. Experimental results show that an active contour model based on the new edge stopping function can really overcome the above-mentioned drawbacks.
