hi, i am trying opencv face detection demo with video (opencv sample with sdk) but most of the times its not detection and also gives wrong detection.

When i change that cascade file to haarcascade_frontalface_alt2.xml it slows down my video n does not detect propely.

Any help is appreciated.

  1. Face detection sample implements one of the simplest detection algorithm and it cannot be used in production.

  2. Cascade based face detection is rotation dependent. Are you sure that video/face orientation is right?

thanx a lot..Alexander Smorkalov ... problem of wrong detection was bcoz of orientation. But i m still facing prob with slow video capture. it hangs video frame n get updated after 3-4 sec and again same case. (As i need to detect eyes,ear & neck i loaded cascade files in 1st activity that is saved as global variable)

If u can give any hint for better video... thnx
