Figure 4
Distribution of histological features and corresponding scatter plots with spectral signature at selected wavelengths. In (a,b), the histology feature is fractal dimension extracted from epithelium, which has strong and significant correlation coefficients with spectral signature at 715 nm. In (c,d), the histology feature is the mean perimeter of Delaunay triangles extracted from nuclei image, which exhibits significant negative correlation with spectral signature at 745 nm.
