The timing figures on the screenshot from K_Anas are shockingly slow... my app on my HTC Desire S with the OpenCV library (here) does 4+ fps...

My demo app on Play Store (eurgh) is here. In the menu the first item takes you to my web page for the app with source code snippets. 1) install OpenCV, 2) get the supplied samples running, 3) edit "Tutorial 2 OpenCVSamples" and drop my code snippets into the frame processing loop.

I claim no credit for the app, it is just a slightly enlarged and adjusted version of the sample which comes with the OpenCV library.

For face detectiion you can use the built in FaceDetector in the Android SDK, It returns face positions and angles in BMPs. But it's not very fast.

You can Also use the javaCV face detection but before to start i recommend you to see this article to see advantages and constarint of some API that you can use and also compare Performance

some

For FaceDetector you can see these links

  1. Link 1
  2. Link 2

Here's a realtime face detection sample using FaceDetector and OpenGL (draws rectangles) which works in Android 2.2

You can also use OpenCV in Android

You'd better try this on Linux (I've tried it on Windows, but failed).

Finally JavaCV (strongly recommended)

There is a sample code of realtime face detection using the camera. See "javacv-src-*.zip" on the download page.
