The most relevant for our purposes is that it is no longer possible to identify a well defined meaning of an image and, therefore, matching based on meaning is impossible. Matching should be replaced by similarity assessment and, in particular, by something close to human preattentive similarity. In this paper we propose a geometric model of similarity measurement that subsumes most of the models proposed for psychological similarity. The interaction between the user and the system should be such as to make this geometry as evident and intuitive as possible. The semiotics perspective - Caliani, Pala et al.
Similarity is a geometer.
