Table 8.

The AUC results of different feature types (T: texture, S: shape, TS: texture+shape) under the best edge detection threshold t, all with $LB{P}_{8,1}^{\mathit{pca}}$ (32) as the local descriptors. Significance test results are in the last column based on DeLong test at p = 0.05 level (>: left setting is better; ≈: comparable performance.)
