Accuracy of detectMultiScale + what are face databases of haarcascade_frontalface_alt.xml

HI all,

1) I would like to know the accuracy of detectMultiScale fucntion in Haar classifier of OpenCV

I understand that the detectMultiScale is using traing dataset of haarcascade_frontalface_alt.xml (in installed folder of Opencv), however, I cannot find any information about the accuracy of this fuction. Say: the detection rate. 2) I cannot find the names of training sets which are used to make haarcascade_frontalface_alt.xml as well.

In general, I want to have some numbers (98%, 95%...) about accuracy of detectMultiScale .

many thanks.
