Detailed Description

A facerecognizer based on EigenFace and FischerFace algorithms.

Currently it just supports detection on fixed scene (detect()) and does not support multiscale detection. This is due to the fact that class for cascade classifier - ODCascadeDetector supports multiscale detection and can be easily integrated with this recognizer - first by finding face using the Cascade and then applying this recognizer on that detected window. This is faster than trying to perform recognition on each multiscale window.
