iv. Correction of Visible-induced Infrared Luminescence Images
The workflow for the correction of VIL images is designed to carry out correction for the
factors affecting visible-induced infrared luminescence images, as summarised in Table 3-1
and discussed in Chapter 1, and using the data collected as a result of the acquisition
protocols outlined in Chapter 2. Figure 3-79 shows a schematic of the workflow developed in
the nip2 software, indicating the transformations/corrections to be applied.
