Detailed Description

template<class TFixedImage, class TMovingImage>
class itk::NormalizedCorrelationImageToImageMetric< TFixedImage, TMovingImage >

Computes similarity between two images to be registered.

This metric computes the correlation between pixels in the fixed image and pixels in the moving image. The spatial correspondance between fixed and moving image is established through a Transform. Pixel values are taken from the fixed image, their positions are mapped to the moving image and result in general in non-grid position on it. Values at these non-grid position of the moving image are interpolated using a user-selected Interpolator. The correlation is normalized by the autocorrelations of both the fixed and moving images.
