Table 4 Ground-truth .mat.mat files labelled by neurosurgeons as described in the Methods section. The table describes only the ground-truths for the hyperspectral data obtained with the Headwall and Ximea hyperspectral cameras. 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”.
