说明：  图像阈值法分割综述：图像分割是一个经典的难题，由于图像分割的复杂性，图像分割的方法很多也很难有一个通用的方法。该文主要是 时图像阈值法分割的一个综述，叙述了阈值法分割的一些方法。最后对这些算法做了一个总结，以及时阂值法分割的期望
(Image thresholding segmentation Roundup: Image segmentation is a classic problem, due to the complexity, image segmentation method for image segmentation are many and difficult to have a common approach. This article is mainly an overview of the image thresholding segmentation, described methods for segmentation threshold method. Finally, these algorithms do a summary, and when thresholds Segmentation expectations)
