%TVDENOISE Total variation grayscale and color image denoising % u = TVDENOISE(f,lambda) denoises the input image f. The smaller % the parameter lambda, the stronger the denoising. % % The output u approximately minimizes the Rudin-Osher-Fatemi (ROF)

本程序计算局部窗口的累积直方图，可用于驱动水平集和纹理分割- in this test program, we calculate the cumulative histogram in a local window centered at each pixel,this local cumulative histogram can be used to drive the level set for image and texture segmentation.

代码的sbseg’是一个非常快速的图像分割，由陈，esedoglu最初提出的变分模型的实现，以及Nikolova。分割模型和它的分裂Bregman方法数值解是在分裂Bregman方法本文几何应用描述：重建，分割和表面由汤姆德斯坦，沙维尔布列松，和斯坦利Osher。-The code ‘sbseg’ is an extremely fast implementation of the variational model for image segmentation originally propo
