This app has 4 different modes of visualizing object movement with the iPhone's camera in real-time.

Touch mode uses a very robust and state-of-the-art tracker designed by Kaihua Zhang, Lei Zhang, and Ming-Hsuan Yang. The official website has source code, documentation, and additional testing demos.

This mode uses background subtraction techniques to locate moving objects in the iPhone camera's view. There is also a mask version of this mode to see where exactly foreground objects appear on top of the background model.
