A new image similarity measure based on ordinal correlation
Bogdan Cramariuc, Ilya Shmulevich, Moncef Gabbouj, Anu M. Makela · 2002
We propose an ordinal-based measure of image similarity. This measure is based on a previously developed general framework for image correspondence and incorporates region-based spatial information. The measure is capable of taking into account differences between images at various scales. Several examples are presented and the measure is evaluated on a set of test images.
