Hu不变矩。本程序用于计算图像的Hu矩特征。该程序不能在5.3版本下运行，必须在6.5以上版本中运行。-Hu moment invariants. This procedure is used to calculate the image of Hu moment features. The program can not run under version 5.3 must be running version 6.5 above.

这个程序主要是用IPLIMAGE类型实现的HU不变矩的最优算法，可以直接运行。-This program is mainly used IPLIMAGE type HU invariant moments achieve optimal algorithm can be run directly.

可以计算图片的七个hu不变矩的matlab程序，里面含例子(Seven Hu moments of invariance for calculating a picture)
