用于计算HU 的7个不变矩和RADON的2、3阶不变矩。网站中有C++写的RADON变换，但西北工业大学的一名教授使用RADON变换构建了这种新型的不变距，可以降低图象的维数，计算速度较快。算法详情可参考他的文献。-used in the calculation of the seven RADON unchanged moments and the 2,3-order moment invariants. Web site is written in C RADON transform, bu

一个实现检测图像轮廓Hu矩的算法，可以输出全部的7阶矩-A realization of the image contour detection algorithm Hu moments, you can output the entire 7 th moment

基于7个hu不变矩的图像匹配，基于7个hu不变矩的图像匹配-Image matching based on 7 hu invariant moments，Image matching based on 7 hu invariant moments

胡氏不变矩，matlab程序，稳定运行，能区分两张图片的不同-Hu invariant moments, matlab program, stable operation, can distinguish between two different images
