in the documentation I found the parameter (update,...) for IEVisionFaceRecognizer.train The help says: "If true and if supported by the algorithm this updates instead of re-train the recognizer."
But I'm not able to find out which of the three reconizers is able to perform updates.
The Local Binary Patterns Histograms (LBPH) recognizer can be updated. For the Eigenfaces and Fisherfaces method, this is algorithmically not possible.
So, you can only set "update" the parameter to true if you called selectLBPHFaceRecognizer.
