Last week we discovered how to perform histogram matching. Using histogram matching, we can take the color distribution of one image and match it to another.

A practical, real-world application of color matching is to perform basic color correction through color constancy. The goal of color constancy is to perceive the colors of objects correctly regardless of differences in light sources, illumination, etc. (which, as you can imagine, is easier said than done).
