Illumination Source Chromaticity Estimation (ISC)

The algorithm is implemented for Scilab link
Using SIP tool box link
ISC code link
We have used Scilab 4.2.2, SIP 0.4, in OpenSuse Linux
This software corresponds to the paper: Illumination Source Chromaticity Estimation Based on Spherical Coordinates in RGB, Ramón Moreno, Manuel Graña, Alicia d’Anjou, Electronics Letters accepted dec. 2010.
Abstract: Spherical coordinates in the RGB color space provide direct chromatic information. In this letter we propose a novel method that uses this information for illumination source chromaticity (ISC) estimation. We test our method on synthetic images whose ISC is known. This allows a quantitative comparison with a state of the art algorithm. Our algorithm improves over the competing algorithm.
