Abstract
This paper explores the use of joint colour and near-infrared
(NIR) information for feature based matching and image registration.
In particular, we investigate multispectral generalisations
of two popular interest point detectors (Harris and
difference of Gaussians), and show that these give a marked
improvement in performance when the extra NIR channel is
available. We also look at the problem of multimodal RGB to
NIR registration, and propose a variant of the SIFT descriptor
that gives improved performance.
