This generates monochrome images based on the output from a single channel (the red channel for VIL images). This is the procedure described as “mono-izing” in Chapter 1. 7) The resultant images can be observed in K9 (Figure 3-82). Image registration: aligning the calibrated VIS image and VIL image. 8) Click on the “align” tab and scroll right. Column B registers the VIS and the VIL images (Figure 3-83). 9) Two sets of images are observed to allow the independent registration of the Spectralon diffuse reflectance standards in the images containing these (B2) and the images themselves (B3). 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 VIL images (as in Figure 3-83). 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. VIL images; (c) Where the images used for calibration are not the same images to be calibrated, either because it is a “twin” image not containing the standards or another frame taken with the same camera and lighting conditions. This may be the situation if carrying out work in the field where site constraints may not allow the standards to be easily included in the frame or if batch processing a number of different frames taken with the same camera and lighting conditions.
