Region特征：

1. count_obj (Regions, Number)
   
2. for J := 1 to Number by 1
   
3.     select_obj (Regions, Region, J)
   
4.     get_features (Region, Features)
   
5.     add_sample_class_mlp (MLPHandle, Features, Class)
   
6. endfor

get_features函数如下：

1. select_obj (Region, SingleRegion, 1)
   
2. circularity (SingleRegion, Circularity)
   
3. roundness (SingleRegion, Distance, Sigma, Roundness, Sides)
   
4. moments_region_central_invar (SingleRegion, PSI1, PSI2, PSI3, PSI4)
   
5. Features := [Circularity,Roundness,PSI1,PSI2,PSI3,PSI4]
