canny检测器是很有效的边缘检测器，该函数可以实现对目标图像的边缘提取。该方法总结如下：1.图像使用带有指定标准差的高斯滤波器来平滑，以此减少噪声；2.在每一点计算局部梯度和边缘方向；3.第二步中确定的边缘点会导致梯度幅度图像中出现脊，然后追踪所有脊的顶部，并将所有不再脊顶部的像素设置为0；4.执行边缘链接-canny detector is very effective edge detector, this function can be achieved on the target image edge detection. This method is summarized as follows: 1. Image used with the specified standard deviation of the Gaussian filter to smooth out, thereby reducing the noise 2. In the calculation of each point of local gradient and edge direction 3. The second step in determining the edge points will led to the image gradient magnitude ridge appears, and then keep track of all of the top of the ridge, and ridge at the top of all the pixels are no longer set to 0 4. the implementation of the edge link

用如求直立主图统计程序。RGB有3个座标，分别是R,G,B，其值从0－255。把0－255分成4段，那么每个座标有4种取值，共可以表示4*4*4＝64种颜色。程序中主要是histogram函数,它有两个参数，第1个参数是一个64位数组，每一位表示一种颜色，其值是该颜色出现的次数。另外两个函数numbercolor是对每个像素计算它的颜色值，fenduan是对参数x返回0－255中的某一段。主函数测试一副图片的颜色直方图的统计。-Used as the main map for vertical statistical procedures. RGB has three coordinates, namely R, G, B, its value from 0-255. The 0-255 is divided into 4, then there are four kinds of each coordinates value, can indicate a total of 4* 4* 4 = 64 kinds of colors. Process is mainly histogram function, it has two parameters, the first a parameter is a 64-digit group, each and every one expressed a different color, its value is the number of the color appears. The other two function numbercolor is calculated for each pixel its color value, fenduan of parameters x the return of a certain period of 0-255. The main function to test a picture of the color histogram statistics.

Doris整个工程文件，包括利用Doris进行影像配准，干涉图生成，DEM生成，是对SAR影像干涉处理的绝佳代码-Doris whole project documents, including the use of Doris for image registration, interferogram generation, DEM generation, is an excellent SAR image processing code for intervention

在16位dos下显示1280x1024图像的图形程序，采用刷屏技术，刷新率有些低，不过这大概是dos下的极限了。有兴趣的朋友可以来看看。-in 16 1280x1024 dos shown graphic images of procedures used Shuabing technology, some of the low refresh rate, but it is probably dos under the limit. Interested friends can come.

仅供参考！实现了基本的数字识别，而且采用了当前最新的特征提取算法，所以使用起来速度很快，识别率也比较高！-Only for reference! Have realized the basic figure is discerned, and has adopted the present newest characteristic to draw algorithms, so it is very fast to use, the discerning rate is higher!
