There is a vast array of different transformations and algorithms for achieving color normalization and a limited list is presented here. The performance of an algorithm is dependent on the task and one algorithm which performs better than another in one task might perform worse in another (no free lunch theorem). Additionally, the choice of the algorithm depends on the preferences of the user for the end-result, e.g. they may want a more natural-looking color image. WebThe hardest step, and the one we will focus on optimizing, is Step 1 -- the estimation of the ambient light. Once the ambient light is known, then correcting the colors in the image …
