用摄像头画画 Camera Hand Drawing

This is a program I recently developed. It tracks the fingertips to draw. 

The frame image in the video are synthesis by the virtual patterns and the real scenes. 

The program could detect a real paper in the scenes, and the pattern drawing on the paper will be following the paper's movement. 

You can also create a rectangle as a virtual paper for drawing.

This is the demo I published on November 15th 2012

Computer vision is one of the fields that I am really interested in. I'd like to keep researching on it.
