Point2D< int >	nrt::findMaxLocation (Image< PixType > const &src)
	Find the maximum location in the image.
template<class PixType >
Point2D< int >	nrt::findMinLocation (Image< PixType > const &src)
	Find the minimum location in the image.
template<NRT_MACRO_PROMOTE_PIX(double) >
DestType const	nrt::mean (Image< PixType > const &im)
	Get the average of all input pixels.
template<NRT_MACRO_PROMOTE_PIX(double) >
DestType const	nrt::stdev (Image< PixType > const &im)
	Compute standard deviation of pixel values over image.
template<NRT_MACRO_PROMOTE_PIX(double) >
DestType const	nrt::variance (Image< PixType > const &im)
	Compute variance of pixel values over image.
template<NRT_MACRO_PROMOTE_PIX(double) >
DestType const	nrt::sum (Image< PixType > const &im)
	Returns the sum of all input pixels.
template<class promo = float, class T >
nrt::promote< T, promo >::type const	nrt::normalizedCrossCorrelation (Image< nrt::PixGray< T > > const &im1, Image< nrt::PixGray< T > > const &im2)
	Returns the normalized cross-correlation between two images of same dims, images should have zero mean.
