http://en.wikipedia.org/wiki/Difference_of_Gaussiansyou can try to simply use two
 
RecursiveGaussianImageFilter with two different sigmas, and substract the 
smoothed images with DifferenceImageFilter.Regards.

DifferenceImageFilter is specialized for making comparisons between two images to
 tell if they are the same -- SubtractImageFilter may be more appropriate.

There is a good example at the end of the ITK Software Guide on creating 
composite filters.
