Detailed Description

Implements pixel-wise the computation of squared difference.

This filter is parameterized over the types of the two input images and the type of the output image.

Numeric conversions (castings) are done by the C++ defaults.

The filter will walk over all the pixels in the two input images, and for each one of them it will do the following:

cast the input 1 pixel value to double

cast the input 2 pixel value to double

compute the difference of the two pixel values

compute the square of the difference

cast the double value resulting from sqr() to the pixel type of the output image

store the casted value into the output image.

The filter expect all images to have the same dimension (e.g. all 2D, or all 3D, or all ND)

See also: itk::simple::SquaredDifference for the procedural interface; itk::SquaredDifferenceImageFilter for the Doxygen on the original ITK class.
