Camera Color Correction Toolbox

A toolbox to calculate the optimal color correction matrix that maps the camera responses to the target values.

Following color correction models are supported:

• Linear transformation
• Polynomial regression
• Root-polynomial regression

MATLAB version R2018b or higher with Image Processing Toolbox is recommended in order to implement images.roi object. But for other versions the normal rectangle function works well too. Optimization Toolbox is required.

Demo

• This gif is only for demonstration purpose. The source image suffered from lots of color degradation, that is why the result looks very bad :joy:
• Please see /demo/ folder for more detailed usage guides.
