28) Figure 3-90 shows a comparison of the images before (right) and after subtraction of the
ambient stray radiation (left).
29) The sRGB (or RGB16) VIL images corrected for ambient stray radiation can be viewed
and saved in the “results” tab. Images of the mathematically reconstructed ambient stray
radiation are also available in this column of the “results” tab (see later).
Correcting for the “pigment-binder’” interaction (Kubelka-Munk)
30) Click on the “vilkm” tab (Figure 3-91). Column J] uses the corrected VIS, IRR and VIL
images (automatically carried over from the “viscalib”, “specden” and “vilstray” tabs,
respectively) to calculate y, a function which expresses the extent to which the pigment
particles absorb the light emitted by the luminescent materials (for more details see
Chapter 1).
