Region-based Graph Cut Algorithm for Mumford-Shah Image Segmentation Model

Abstract: 在Egil Bae和Tai Xue-Cheng提出的图切割算法基础上,给出了一种改进算法用于求解Mumford-Shah图像分割模型。首先利用Mean Shift算法对原始图像进行过分割,基于过分割产生的小区域构造恰当的图,使得分割问题转化为求特定图的最小切割问题。数值实验结果显示,直接利用Mean Shift算法分割的效果不理想,本方法保持了与Egil Bae和Tai Xue-Cheng方法相类似的分割效果,而运算效率却有了很大提高。
