[Special Effectsregionbased_seg_demo

Description: This code implements the well-known Chan-Vese segmentation algorithm from the paper "Active Contours Without Edges." This technique deforms an initial curve so that it separates foreground from background based on the means of the two regions. The technique is very robust to initialization and gives very nice results when there is a difference between the foreground and background means. This code uses active contours and level sets in the implementation. It could also serve as a good framework for implementing all kinds of region-based active contour energies. 1.) Download 2.)

Description: 迭代法是基于逼近的思想,逼近的目标是使得:前景和背景的平均灰度值的平均值即为阈值。该方法的原理是:如果用某一阈值分割出的图像,其两部分平均值的中值,正好等于该阈值,那么这个阈值就是所求的阈值。-Iterative method is based on the approximation of the idea of ​ ​ approaching the goal is to make: the foreground and background is the average of the average gray value threshold. The principle is: if a threshold image segmentation, the average value of two parts, exactly equal to the threshold, then the threshold is the threshold requirements.
