This paper aims at presenting some problems that everyone could experience in the process of image target-based color correction (CC). We have acquired a set of images using a color checker, here we present some measures of these image before and after the color correction and we compare them with the actual values of the color checker. Comments about the results and their departures from the scene are reported together with the changes after color correction. It is shown how real scene acquisitions are subject to many issues that makes color correction process very far from the idealized colorimetric ideas.

Abstract
This paper aims at presenting some problems that everyone could experience in the process of image target-based color correction (CC). We have acquired a set of images using a color checker, here we present some measures of these image before and after the color correction and we compare them with the actual values of the color checker. Comments about the results and their departures from the scene are reported together with the changes after color correction. It is shown how real scene acquisitions are subject to many issues that makes color correction process very far from the idealized colorimetric ideas.| File | Dimensione | Formato | |
