Macbeth Chart module

Color Correction Model

Introduction

ColorCharts are a tool for calibrating the color profile of camera, which not only depends on the intrinsic and extrinsic parameters of camera but also on the lighting conditions. This is done by taking the image of a chart, such that the value of its colors present in it known, in the image the color values changes depeding on many variables, this gives us the colors initially present and the colors that are present in the image, based on this information we can apply any suitable algorithm to find the actual color of all the objects present in the image.
