Color constancy using fractals

At first glance, the juxtaposition of color constancy, a topic which involves negating the effects of lighting and changes in dynamic range with fractals, a topic usually identified with dynamical systems or image compression, may seem odd. We show here that this is not the case. In the process, we show that there is surprisingly little to do to convert a fractal decompression algorithm into an algorithm for color constancy, and that even such a discontinuous mapping can effect a change in dynamic range that makes sense to the eve. First we will go over the two topics in sufficient detail to support this argument. We will first recount the Retinex algorithm, which is our method for approaching color constancy. There are two published types, we will use the algorithm known as McCann'99 [1]. Once we have established the basics of this algorithm. we will review the theory and execution of a rudimentary fractal compression and decompression algorithm. Finally, with this around work in place, we will show how to put the two algorithms together, and present our results and our pointers at future work.
