用C＋＋写的归一化不变矩程序，将不变矩封装成一个类，是因为程序所需要，怎么使用，注释里面有。还有就是，这个程序只能计算8位灰度图的不变矩。 -Using C　　 to write the normalized moment invariants procedures, will be packaged into a moment invariants category, because the procedure is necessary, how to use, notes there are. There is, this procedure can only be calculated 8-bit grayscale of moment invariants.
