cas A NI 7 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.
