Seminar on the Spectral Sudoku of Halftone Dots

Today at 4 pm Eastern Time Dr. J. A. Stephen Viggiano will present a seminar at the Ceneter for Imaging Science at RIT. The seminar is entitled: "Spectral Sudoku of Halftone Dots: The New Math Catches Up Wth Print Color".

The abstract is intriguing:

"When the colors that come of a printer don't resemble what's displayed on the monitor, better prediction of print color may be needed. These models are also useful for simulating the system, even before it can be built. Paradigms for color print modeling will be examined and classified. Challenges will also be discussed.

Modern algebra provides a link between a popular puzzle and the colors produced by printers. One of the modeling paradigms uses Hilbert-like spaces where, depending on the image microstructure, vector addition may or may not hold. Other models derived include a class that account for multiple scatter. The latter are spatial generalizations of the Kubelka-Munk model."
