Regisration of hyperspectral and trichromatic images via cross cumulative residual entropy maximisation

In this paper we address the problem of image fusion between imagery acquired by trichromatic sensors and hyperspectral imagers. We do this by presenting a method aimed at registering a high-resolution trichromatic image with lower resolution hyperspectral data. The method presented here maps the hyperspectral image into the grayscale image so as to employ the cross cumulative residual entropy for purposes of multimodal registration. We illustrate the utility of our approach by presenting registration results on a set of surveillance image pairs consisting of a set of high-oblique colour and hyperspectral images.
