1、编制程序显示印章图像（24位真彩色位图）；

2、读出位图中每一像素点的（R，G，B）样本值；

3、以RGB其中某两个（或三个）为坐标，取一定数量的图像点为分析样本，分析其坐标系中的分布；

4、采用本章学习的方法找到分类判别函数，对这些样本进行分类；（要求首先将印章与底纹区分，如有可能将印章、底纹、签字区分）

5、将分类后的结果标记到原始图像上，检查其效果。

-1, the preparation procedures showed that the seal image (24-bit true color bitmap)　2, read out each bitmap pixel (R, G, B) sample value　3 to RGB which a two (or three ) for the coordinates, take a certain number of image points for the analysis of samples, analysis of its coordinate system of distribution　4, the method used in this chapter to learn to find discriminant function classification of these samples for classification　(required first to distinguish between the seal and Shading, if possible, will seal, Shading, signatures to distinguish between) 5, will be the result of classification markings to the original image to check its effectiveness.
