TLDR
A new method is described for automatic control point selection and matching that can produce subpixel registration accuracy and is demonstrated by registration of SPOT and Landsat TM images.Abstract:
A new method is described for automatic control point selection and matching. First, reference and sensed images are segmented and closed-boundary regions are extracted. Each region is represented by a set of affine-invariant moment-based features. Correspondence between the regions is then established by a two-stage matching algorithm that works both in the feature space and in the image space. Centers of gravity of corresponding regions are used as control points. A practical use of the proposed method is demonstrated by registration of SPOT and Landsat TM images. It is shown that the authors' method can produce subpixel registration accuracy. >read more

A fast direct Fourier-based algorithm for subpixel registration of images
TL;DR: Experimental data presented here show that the new algorithm yields superior registration precision in the presence of aliasing when compared to several earlier methods and has comparable precision to the iterative method of P. Thevenaz et al. (1998).

On the independence of rotation moment invariants
TL;DR: It is shown that for any set of invariants there exists a relatively small basis by means of which all other invariants can be generated and how to prove its independence and completeness is presented.
