Hello, I am trying to detect multiple faces with Matlab built-in viola jones face detection.But in some cases it gives me false detection. Is that possible to train my own classifier and then integrate into the Matlab classification model itself in oder to reduce the false detections?
thank you.

You Can Apply Threshold on boundary Box. it removes the small part detection. You can Also Apply Margin in viola Jones Directory In This Case.

Yes, the VJ face detection is a particular trained detector. You can train your own detector within exactly the same setup; see http://www.mathworks.com/help/vision/ug/train-a-cascade-object-detector.html

I have used the "FrontalFaceCart" and "ProfileFace" in parallel and in some cases I got overlapping boxes. How can I merge them into one? And any idea why it's not detecting the second person in the attached photo?
