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。

The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

3.画椭圆ellipse 4.利用ellipse and rectangle 画图 5.一个最优美的图案 6.输入3个数a,b,c,按大小顺序输出 :输入数组,最大的与第一个元素交换,最小的与最后一个元素交换,输出数组。 7.有n个整数,使其前面各数顺序向后移m个位置,最后m个数变成最前面的m个数
