Computer Based Correlation of the Texture of P63 Expressed Nuclei with Histological Tumour Grade, in Laryngeal Carcinomas

Figure 4

ROC curve: using best features combination in the logistic regression equation and the LOO cross-validation method, highest prediction accuracy was achieved (AUC = 0.87, features involved: %P63 expressed nuclei, Angular Second Moment^r, Correlation^a, Inverse Difference Moment^r, Sum Entropy^r, Solidity, and Radial Distance range). : average and : range of the feature over four directions (0°, 45°, 90°, and 135°).
