Creates a FaceDetector, configured with the size of the images to be analysed and the maximum number of faces that can be detected.

Usage

From source file:Main.java

private static PointF findFaceMid(Bitmap in) {
    PointF mid = new PointF();
    Bitmap bitmap565 = in.copy(Bitmap.Config.RGB_565, true);

    FaceDetector fd = new FaceDetector(in.getWidth(), in.getHeight(), 1);
    FaceDetector.Face[] faces = new FaceDetector.Face[1];
    fd.findFaces(bitmap565, faces);/*  w  ww  .j a va2  s.  co  m*/

    FaceDetector.Face face = faces[0];
    if (face != null) {
        try {
            face.getMidPoint(mid);
            return mid;
        } catch (NullPointerException n) {
