[Insight-users] Comparing Images Computationally

[Luis Ibanez]

Hi Neha,

Usual options for comparing two images are:

1) The DifferenceImageFilter
http://www . itk . org/Insight/Doxygen/html/classitk_1_1DifferenceImageFilter . html

2) The SquaredDifferenceImageFilter
http://www . itk . org/Insight/Doxygen/html/classitk_1_1SquaredDifferenceImageFilter . html


The filter (1) provides a tolerance, around pixels,
you may want to reduce the tolerance in your case.
This is the filter used by the regresion testing system
in ITK.


The filter (2) is simply the sum of squared differences
between  two images.




Regards,


    Luis
