Fast Retinex for color image enhancement: methods and algorithms
Analysa M. Gonzales, Artyom M. Grigoryan · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2015
There exist various implementations of the Retinex algorithm first developed by Edwin H. Land and Mcann, all of which allow for varying amounts of user control of specifications, intermediary steps and filters, and different forms of application. The purpose of this project is to study various existing algorithms implementing multiscale Retinex (and color restoration) in order to understand how they differ, their various advantages and limitations, and overall which are the most powerful methods. From this study, we attempted to improve upon an existing algorithm in order to greatly reduce processing time while still achieving a good result which we would judge using a new measure of color constancy.
