RBCs optical images and the corresponding hyperspectral image for healthy (left panels) and ASD (right panels) children. In yellow box a selected RBC for which an enlarged view is given below, where it is clearly seen the satisfactory matching of the optical and hyperspectral images. Coloured areas indicate regions whose reflectance spectra match with the spectral end-members of the library, as shown in Supplementary Fig. 1.
