Loading the inputimages converted from RAW:
— VIL image for generating the calibration and associated flat-field image (if available).
— VIL to be calibrated (can be the same as above image or another image taken with
the same camera and under the same lighting conditions) and associated flat-field
image (if available).
Converting the images to linear light (XYZ) using the embedded ICC profile(s).
Applying a flat-field correction to the images (if this option is checked).
Generating monochrome images based on the output from a single channel (red
channel for VIL images).
Image registration: aligning the calibrated IRR image and VIL image.
Mathematically reconstructing the ambient stray radiation:
— From the IRR image and the Spectralon greyscale on the VIL image.
Subtracting the ambient stray radiation from the VIL image.
Correcting for the “pigment-binder” interaction (Kubelka-Munk)
Applying an output ICC profile which converts the calibrated VIL image to sRGB (or
RGB16) colour space.
