Table 3 Pre-processed .mat files following the data preprocessing steps described in the Methods section. Only the data obtained with the Headwall and Ximea hyperspectral cameras are described. Each patient is identified with an integer x number. For the same patient, multiple captures can be performed, with y indicating the capture number. The “*” mark is a wildcard indicating that the file suffix is “_cropped_Pre-processed”.
