threshold is a key technique for the segmentation and edge detection in an image for image processing. Here in this file the threshold is on the based of the maximum entropy of an image using shannon entropy method.

图像分割就是把图像分成若干个特定的、具有独特性质的区域并提出感兴趣目标的技术和过程。它是由图像处理到图像分析的关键步骤。现有的图像分割方法主要分以下几类：基于阈值的分割方法、基于区域的分割方法、基于边缘的分割方法-Image segmentation is the image into a number of specific, region with unique properties and proposed technologies and processes target of inte
