Classification performance using subdiffuse reflectance ($f_x=1.37{\mathrm{mm}}^{-1}$, $\lambda =490\mathrm{nm}$) and evaluated by ROC curve analysis for (a) adipose, (b) connective, and (c) FCD, versus the three malignant tissue subtypes. Classification used a linear SVM classifier, correlation-based feature selection with grid-searching, fivefold CV, sample size matching, and averaging over $n=100$ iterations. At most 11 texture features were included in each classification.
