On the Monotonicity of relative entropy: A Comparative Study of Petz's and Uhlmann's Approaches
Santiago Matheus, Francesco Bottacin, Edoardo Provenzi
We revisit the monotonicity of relative entropy under the action of quantum channels, a foundational result in quantum information theory. Among the several available proofs, we fo…
Split-quaternions for perceptual white balance
Michel Berthier, Nicoletta Prencipe, Edoardo Provenzi
We propose a perceptual chromatic adaptation transform for white balance that makes use of split-quaternions. The novelty of the present work, which is motivated by a recently deve…
Geometry of color perception. Part 1: Structures and metrics of a homogeneous color space
Edoardo Provenzi
This is the first half of a two-part paper dealing with the geometry of color perception. Here we analyze in detail the seminal 1974 work by H.L. Resnikoff, who showed that there a…
The relativity of color perception
Michel Berthier, Valerie Garcin, Nicoletta Prencipe +1
Physical colors, i.e. reflected or emitted lights entering the eyes from a visual environment, are converted into perceived colors sensed by humans by neurophysiological mechanisms…
Quantum measurement and color perception: theory and applications
Michel Berthier, Edoardo Provenzi
In this paper we make a systematic use of the quantum measurement theory to describe perceived colors and analyze some of their fundamental properties. After motivating the natural…
A quantum information-based refoundation of color perception concepts
Michel Berthier, Nicoletta Prencipe, Edoardo Provenzi
In this paper we deal with the problem of overcoming the intuitive definition of several color perception attributes by replacing them with novel mathematically rigorous ones. Our…
