1) Loading the inputimages converted from RAW: — UVL image for generating the calibration and associated flat-field image (if available). — UVL 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). Applying the camera colour calibration and white-point adjustment to the UVL images. Image registration: aligning the calibrated VIS image and UVL image. Mathematically reconstructing the ambient stray radiation: — From the VIS image and the Spectralon greyscale on the UVL image. Subtracting the ambient stray radiation from the UVL image. Correcting for the “pigment-binder” interaction (Kubelka-Munk). Applying an output ICC profile which converts the calibrated UVL image to sRGB (or RGB16) colour space. 152 kanal
