OTSU 算法可以说是自适应计算单阈值（用来转换灰度图像为二值图像）的简单高效方法。算法对输入的灰度图像的直方图进行分析，将直方图分成两个部分，使得两部分之间的距离最大。划分点就是求得的阈值。-Otsu algorithm can be said to be adaptive to calculate the single threshold (for converting images to gray scale image 2) simple Efficient methods. Algorithm for the importation of gray image histogram analysis of histogram is divided into two parts. makes two of the distance between the largest. Demarcation point out the threshold.

基于图像直方图均衡化的公式来编程。像素一共分为256个灰度阶，每个灰度阶用数组的一个相应nk[？]来储存它的个数，然后计算tk[？]。-Based on image histogram equalization formula programming. Pixel is divided into a total of 256 gray-scale bands, each of the gray band with a corresponding array nk [? ] To store the number of it, and then calculating tk [? ].

沃尔什（Walsh）变换是一种可分离变换，广泛应用于图像处理。本代码实现了图像Walsh变换，非常经典，带图片可测试.-Walsh (Walsh) is a separable transform transform, which are widely used in image processing. Implementation of the code of the image Walsh transform, very classic, with pictures can be tested.

背景 航空公司的货运飞机往返于各个国家和货物分理中心之间，分理中心的货物运送到各个国家，再将各个国家发出的货物送到分理中心。 分理中心非常庞大，每个国家都有一个自己的货运站，每个货运站有两个平台用于堆放货物。其中 A 平台用于堆放运送到该国的货物，而 B 平台堆放着其它国家的货物。各个国家的货运站排成一个环形。 （详细见内部文档）-Background Airlines cargo flights to and from various countries and goods in the sub-Li centers, sub-arguments centered delivery of goods to various countries, and then sent to various countries of the goods issued by Sub-Center. Sub-Li center is very large, each country has its own cargo terminal, each terminal has two platforms used to stack cargo. Where A platform for stacking goods shipped to the country, while the B platform, goods piled up in other countries. Each country" s air cargo terminals arranged in a ring.
