Summary:Abstract: "This paper introduces the use of a multi-variate correlation function for region-based image matching and extends it to a modified cross-correlation function that works well when matching image areas are required have [sic] the same intensity contrast. It also shows that the multivariate case is a straightforward generalisation of the monochrome image case. Experiments with both MRI and RGB colour imagery are shown, along with comparisons with the Euclidean, Manhatten and L[subscript infinity] matching metrics."
