I want to ask immediate , basic but important question for me. I want to learn function of detectMultiScale() and how to use it in order to write face detection code in android. I looked http://docs.opencv.org/modules/objdetect/doc/cascade_classification.html but I could not understand clearly. Thanks for your advice.

opencv4android comes with a face-detection sample using lbpcascade.

First of all, since you are using android, you will have to look at the java wrapper class documentation right here. If you then click on objdetect and cascade classifier in the navigation menu you will notice that it is supported! However don't expect this for every single OpenCV function out there.

As to applying this technique in android, there should be samples out there.

And also take a look at the android samples!
