I have suceesfully drew a rectanlge over the face in Android. Inorder to crop the selected face I used the following code:
Mat cropped_face = image;
Rect cropped= new Rect(facesArray[i].tl(), facesArray[i].br());
cropped_face = new Mat(image,cropped);
The 'image' variable holds the original image from the camera.
I encountered following error on the last line of code.
AndroidRuntime: FATAL EXCEPTION: Thread-6
