Abstract
In this paper we assess the quality of colorimetric calibration of HDR images captured using the multi-exposure technique. Three cameras were used to take HDR photographs of 4 scenes containing a color checker chart (XRite) and custom color patches. These were also measured using a spectrometer to provide ground truth data. One of the scenes was then used as a training for 2 camera calibration models, one including and one without the black level. The parameters of the models were fitted by optimizing an error function based on the CIE2000 ∆E color error measure. For the remaining 3 scenes, the accuracy of the fit was verified using the CIE2000 ∆E error between the measured and predicted color values. Our results indicate that a very good fit can be achieved, in the range of 0.8 to 2.1 ∆E using the model without black level.
