Title:
Mathematical psychophysics of color perception

Abstract:
Color perception by human beings is a phenomenon that fascinated many scientists, from Newton to Maxwell, through Grassmann and Helmholtz, to quote just the most well-known. In 1920, Schrödinger condensed the findings of his predecessors in an elegant axiomatic system, completed only in 1974 by Reskinoff. In this seminar I'll present a recent model based on a quantum interpretation of the Schrödinger-Resnikoff's axiomatic system. In particular, I'll show two surprising theoretical results: the first is that the Hering opponent theory can be explained within the setting of a "rebit", the real version of a two-state quantum system; the second is the existence of uncertainty rules for chromatic perception. I'll end by discussing a practical application of the model, also unexpected, by showing that the white balance of digital images can be performed through a suitable Lorentz transformation.
