a a et CHARISMA (b) If available, load an image of a uniform reflective board (under the same experimental conditions) for flat fielding into the bottom box on the “targets” thumbnail and check the option to "Flatfield visible-induced IR luminescence with calibration targets image" (Figure 3-81). If this is not available leave this option unchecked. (c) Load the image(s) you want to correct into the top box on the “object” thumbnail (Figure 3-81). This can be the same image as above or another frame (e.g. another frame in a series or a “twin” image not containing the spectralon diffuse reflectance standards, as described in Chapter 2) taken with the same Camera and under the same lighting conditions. If available, load an image of a uniform reflective board (under the same experimental conditions of the image) for flat fielding into the bottom box on the “object” thumbnail (Figure 3-81) and check the option to “Flatfield visible-induced IR luminescence of object image”. If this is not available leave this option unchecked. aloe 21 H2 ID! targets v v <> use_flatfield [7 Flatfield visible-induced IR luminescence with calibration targets image A S x ° eee Pair_flatfield NULL (label ++ " with calibration targets") a v | object label | visible-induced IR luminescence of object use_flatfield { 7 Flatfield visble-induced IR luminescence of object image ] lA lV S| fiatfield | lV ; Pair_flatfield (targets.image) (label ++ " of object") ő Pair. load "visible-induced IR luminescence" Figure 3-81 flat-field correction to the images. 3) (Figure 3-82).
