Abstract
With the proliferation of digital cameras, more consumers are faced with the problem of making color corrections to their pictures, while most picture editors allow some white point, or illuminant, correction and some enhancements, these methods work on the image, as a whole rather than on specific regions or colors. This work describes a simple method, that allows the user the ability to correct specific colors in specific locations in a picture. It is shown that relatively few sample colors are needed to produce a well-behaved interpolation in three-dimensional color spaces. A quantitative measure of performance is obtained by using the method to correct for illumination.
