Android - Face feature detection

Question

Currently I\'m working on an app for Android phones. We want to detect features of a face. The programm should be able to detect the positions of the eyes, the nose, the mouth a

Answer 1

I'm working on a similar project. I did some testing with the FaceDetection API and can tell you that it is not going to help you if you want to detect the eyes, nose, mouth and edges. This API only allow you to detect the eyes. It is useless if you want to implement face recognition because you need more features than just the eyes during the face detect part.

A comment on your first reply: you actually do need face detect. Finding features is part of face detection and getting these features is the first step in a face recognition app. With OpenCV you can use Haar-like features for getting these features (eyes, nose, mouth, etc.).

However I've found it somewhat complicated to use the openCV functions with a separate .cpp file. There is a thing called JNIEXPORT which allows you to edit an Android gallery image with OpenCV functions inside a .cpp file. OpenCV has a sample Haar-like feature detect .cpp file which can be used for face detection (and recognition as a second step with an other algorithm).

Are you developing on windows or linux? I'm using windows and haven't managed to use the tutorial you linked to set up OpenCV with it. However I do have a working windows OpenCV environment in Eclipse and got all samples from OpenCV 2.3.1 working. Maybe we can help each other out and share some information/results? please let me know.
