OpenCV is an “open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in” software.

TD comes with OpenCV built-in via the Python language. OpenCV does represent a significant world of possibilities. However, the move to using Python also represents a significant jump in technical needs. The following tutorial is optional for this reason, however, I do suggest you attempt to get into this world.
