案例介绍

This repo is to implement color adjustment algorithm based on colorchecker.

The main idea of the algorithm is as follows: input a picture with a colorchecker, linearize the input colorchecker colors, and then use the color correction matrix(CCM) to linearly transform the former result to minimize the distance from the standard colorchecker colors. The goal of optimization is the ccm matrix.

After the ccm matrix is calculated, you can enter the picture for correction. The input picture is linearized, then multiplied by the ccm matrix, and then inversely linearized. Note that the rules for linearization and delinearization may be different.
