图像处理中 各种阈值分割的基本算法的实现，包括双峰法 迭代法 大金法（ostu）等等,A variety of image processing in the basic threshold segmentation algorithm, including the bimodal method， iteration method， Daikin (ostu), etc.

matlab基于双峰法求取谷值来分割图像，此方法只适合比较简单的图像，背景最好已经分割了-matlab based bimodal strike valley to image segmentation, this method is only suitable for relatively simple images, backgrounds preferably has divided
