          1) 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.           168 kanal
