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
