Table 7.

The AUC results of employing different global frameworks (MSSP: multi-scale spatial pyramid; SP: spatial pyramid; SD: single 2nd-level spatial division; “\O”: exclude the overlapped blocks) with $LB{P}_{8,1}^{\mathit{pca}}$ (32) as the local descriptors. Here, only the texture properties from the retinal image are encoded. Significance test results are in the last column based on DeLong test at p = 0.05 level (>: left setting is better; ≈: comparable performance.)
