本程序是应用matlab语言提取图像的不变矩输出结果。这是提取经典的七个不变矩的值，速度很快-this program is the application of Matlab language from the moment invariants image output. This is the classic seven from the same value of the moment, very fast

Hu的七个不变矩在图像匹配检索中适用广泛。本代码仅计算图像间Hu的七个矩的D2大小，直观的了解Hu矩的应用-seven moment invariants in image retrieval in the application of broad match. Only the calculation of the code between the image of the seven Hu moments D2 size, intuitive understanding of the app
