Image Registration: Similarity Measure and Preprocessing Method Comparisons
Martin Svedlow, Clare D. McGillem, Paul E. Anuta · IEEE Transactions on Aerospace and Electronic Systems · 1978
An experimental comparison of several similarity measures and preprocessing techniques used for the registration of temporally differing images is carried out. It is found that preprocessing of the images via a gradient operator improves the registration performance. This is in agreement with a derived optimal processor (described in the Appendix) based upon image and temporal difference characteristics.
