Detailed Description

template<typename TFixedImage, typename TMovingImage>
class itk::MeanSquaresHistogramImageToImageMetric< TFixedImage, TMovingImage >

Computes mean squared difference similarity measure between two images to be registered.

This class is templated over the type of the fixed and moving images to be compared.

This metric computes the similarity measure between pixels in the moving image and pixels in the fixed images using a histogram.
