Hi,

I'm trying to classify spot images yet I got a weird results, To simplify 
my situation here is a small example:
If I used two classes 111 and 512 I got this confusion matrix which is 
weird because of the zeros !!! 
      [111] [512] 
[111]   839     0 
[512]     7     0 

After a lot of tests I figure out something, if I rename the class 512 to 
51 or what ever a small number, I got the results bellow which are very 
logical.
      [ 51] [111] 
[ 51] 27624     0 
[111]     0   839  

So I'm guessing that name of the class labels must be less than a threshold 
!!!! Am I right !!!  

Any help please.
Thank you.
