Workflow for the correction of IR and/or UV-reflected images (IRR/UVR) and the
generation of IR and/or UV-reflected false-colour (IRRFC/UVRFC) images.
Check that the all images or other information required in order to run this workspace is
available:
e Calibrated VIS image(s) (including a Spectralon diffuse reflectance grey scale or any
number of Spectralon diffuse reflectance standards as available) obtained by
processing the corresponding visible-reflected image(s) using the workflow for
correction of visible-reflected images (See above);
e Camera output file (TIFF) — IR and/or UV-reflected images (including a Spectralon
diffuse reflectance grey scale or any number of Spectralon diffuse reflectance
standards as available) converted from RAW as per instruction in section a;
e ICC profile for conversion from RAW (contained within the TIFF file);
e Image(s) of uniform reflective board under experimental conditions of IR and/or UV¬
reflected images for flat fielding, if available.
Loading the input images
1) Note that the previous workflow for correction of visible-reflected (VIS) images must
already have been completed prior to running through this workflow. If this has not been
done, return to section i and proceed as directed before continuing.
2) Click on the “input” tab (Figure 3-39), the second row of columns on the left (column E
and F) hold the input images required for this workflow (correction of IR and/or UV¬
reflected images). If these were not uploaded previously, add them as directed below.
