* \class BinaryMagnitudeImageFilter
* \brief Computes the square root of the sum of squares of corresponding input pixels.
*
* This filter is templated 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 walks over all of the pixels in the two input images, and for
* each pixel does the following:
*
* \li cast the input 1 pixel value to \c double
* \li cast the input 2 pixel value to \c double
* \li compute the sum of squares of the two pixel values
* \li compute the square root of the sum
* \li cast the \c double value resulting from \c std::sqrt() to the pixel type of the output image
* \li store the cast value into the output image.
*
* The filter expects all images to have the same dimension
* (e.g. all 2D, or all 3D, or all ND)
*

* \ingroup MultiThreaded
