Similarity Functions for Face Recognition

Enrico Vezzetti and Federica Marcolin

Abstract

Similarity functions are not distances, but functions aimed to evaluate the similarity between two objects. Some of them relate to some other previously explained measures, such as cosine distance. Others are statistical or probabilistic, or rely on fuzzy logic. It has not been possible to provide a comprehensive table with recognition rates, as the data were to different to be compared.
