[2D图形编程] HUandradon
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, but Northwestern University professor using a RADON Transform Construction of this kind of new unchanged from, images can reduce the dimension and fast calculation. Algorithm Details can be found in the literature. (2006-04-26, matlab, 12KB, 下载400次)
