Prerequisites: Fundamentals of color physiology and linear algebra.

Benefits:
Attendees will be able to:

• Learn a completely novel theory of the space of perceived colors.
• Understand a mathematically rigorous way of defining hue, saturation, and lightness.
• Understand how Newton's color circle can be interpreted in the light of this modern theory.
• Understand how Hering's theory can be understood in terms of the quantum-like model.

Course Description
This course introduces the audience to a very recent quantum-relativistic theory of color perception that permits us—among other things—to redefine colorimetric attributes and to perform a non-diagonal white balance. The core concept of this theory is that of space of perceived colors, intended as a structured space with geometrical properties and not simply a collection of color coordinates. After a historical introduction, we arrive to the fundamental, yet almost unnoticed, result of Resnikoff about the importance of hyperbolic geometry in color vision. This allows us to introduce the quantum-relativistic theory in which concepts such as hue, saturation, lightness, color opponency, chromatic adaptation, and white balance assume a totally new meaning.

Intended Audience: educators in color theory, master, PhD students, Post-doc researchers and, in general, researchers in color science. A promising whole new way of interpreting and analyzing colors is taught.

Edoardo Provenzi is full professor of mathematics and applications at the University of Bordeaux, France. He has been working on mathematical modelling of color perception and its applications on image processing since 2004. His work includes both variational methods for color enhancement, with a book published on this subject, and differential geometry models of the space of perceived colors.
