A simple demo app to show the ability of face detection from live view. OpenCV / EmguCV libraries, and Android's build-in algorithms are used to detect and display faces. Some image processing techniques are used internally to optimize the results.
1. Front face is detected as green rectangle.
2. Side face (enabled by option menu, disabled by default) is detected as blue or cyan rectangle.
3. Android build-in face detection result is displayed as white or yellow rectangle.
4. User can change live view's resample size to improve processing speed.
5. User can display debug image (grayed) to observe image quality.
