Face Recognition Problem

greek_face

Good morning,

I'm having a problem with the viola-jones algorithm for detecting faces. I use the an xml file where i load some negative and some positive pictures in order to train. Then i load a test image with a person where i except it's face to be recognised. Unfortunately, i keep getting this error:

Jan 14, 2012 12:06:04 AM WARNING: Caught exception in concurrent execution of Detector (Detector): com.rapidminer.operator.UserError: No data was deliverd at port Detector.model (connected).

When i run the xml file and load the pictures of cancer (the known black images where a tumor is detected), the results are great and the tuor is being recognised correclty.

I'm new in Rapidminer so any help would be appreciated.

Hi,
have you tried the example at this website?

Yesterday I have uploaded an example process and example training set.

Hope this helps.
