[Insight-users] Re: subtract two binary images

[Luis Ibanez]

Hi Alireza,

What is your definition of subtraction in binary ?


If you actually do binary arithmetic on every pixel,
then that should be:

      0 - 0 = 0
      1 - 0 = 1
      0 - 1 = 1      (Note this one!!)
      1 - 1 = 0

Which is equivalent to an Exclusive Or  (XOR) operation.

If this is the operation you want,
then you can use the filter:


           itkXorImageFilter.h


Regards,



     Luis
