13) The sRGB (or RGB16) colour calibrated UVL images can be viewed and saved in the
“results” tab (See later).
Image registration: aligning the calibrated VIS and UVL images.
14) Click on the “align” tab and scroll right. Column A registers the VIS and the UVL images
(Figure 3-68).
15) Two sets of images are observed to allow the independent registration of the Spectralon
diffuse reflectance standards in the images containing these (A2) and the images
themselves (A3). This allows greater flexibility in order to address various scenarios:
(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 UVL
images (as in Figure 3-68). This would be the expected situation in a studio setting;
(b) As above but some alteration in the position of the standards has occurred in the
VIS vs. UVL images;
