cn A B 7 6) Note that if an image of a uniform reflective board under the same experimental conditions of the images was not uploaded (or the options in the "input" tab indicated above were not checked), the images in the “targets” and "object" thumbnails are in linear light but no flat field correction has been applied to them. Generating monochrome images 7) Scroll right to column K. This generates monochrome images (Figure 3-44) based on the output from a single channel (the red channel for IRR images and the blue channel for UVR images). This is the procedure described as “mono-izing” in Chapter 1. 8) The resultant images can be observed in K1 (IRR images) and K2 (UVR images).

Columns D and E register the VIS image and the IRR or UVR images, respectively (Figure 3-45). 10) Two sets of images are observed in each column to allow the independent registration of the Spectralon diffuse reflectance standards in the images containing these (D26 and E8) and the images themselves (D1 and E9). This allows greater flexibility in order to address various scenarios, e.g.: (a) Where the images used for calibration are the same images to be calibrated and no alteration in the position of the standards has occurred in the VIS vs. the IRR and/or UVR images (as in Figure 3-45). This would be the expected situation in a studio setting; Version No. 1.0 140 Date : 14/10/2013
