class itk::CorrelationImageToImageMetricv4< TFixedImage, TMovingImage, TVirtualImage >

Class implementing normalized cross correlation image metric.

Definition of the normalized cross correlation metric used here:

negative square of normalized cross correlation

$C(f, m) = -\frac{<f-\bar{f}, m-\bar{m} >^2}{|f-\bar{f}}|^2 |m-\bar{m}|^2}$

in which, f, m are the vectors of image pixel intensities, $\bar{f}$ and $\bar{m}$ are the mean values of f and m. <,> denotes inner product, $|\cdot|$ denotes the 2-norm of the vector. The minus sign makes the metric to optimize towards its minimal value. Note that this uses the square of the mathematical notion of normalized cross correlation to avoid the square root computation in practice.

Moving image (m) is a function of the parameters (p) of the moving transforms. So $ C(f, m) = C(f, m(p)) $ GetValueAndDerivative will return the value as $ C(f,m) $ and the derivative as

$\frac{d}{dp} C = 2 \frac{<f1, m1>}{|f1|^2 |m1|^2} * ( <f1, \frac{dm}{dp}> - \frac{<f1, m1>}{|m1|^2} < m1, \frac{dm}{dp} > )$

in which, $f1 = f - \bar{f}$ , $m1 = m - \bar{m}$ (Note: there should be a minus sign of $\frac{d}{dp}$ mathematically, which is not in the implementation to match the requirement of the metricv4 optimization framework.

See CorrelationImageToImageMetricv4GetValueAndDerivativeThreader::ProcessPoint for algorithm implementation.

This metric only works with the global transform. It throws an exception if the transform has local support.
