8.6. Application Examples for Face Recognition Systems
The PDBNN face recognizer can be considered an extension of the PDBNN face detector. As mentioned in Section 7.5, PDBNN possesses the OCON structure—that is, there is one subnet in the PDBNN designated for a person to be recognized. For a k-person recognition problem, a PDBNN face recognizer consists of K different subnets. Analogous to the PDBNN detector, a subnet i in the PDBNN recognizer models the distribution of person i only and treats those patterns that do not belong to person i as "non-i" patterns.
The network architecture, learning rules, and performance evaluation of the multiple subnet PDBNNs were discussed in Chapter 7. This section focuses on their application to face recognition; ...
