Finding common points in two consecutive frames or stereo vision.

This was a little test program to understand how to work with the flow functions from OpenCV.

This example is based on the lkdemo demo from OpenCV.

In the first image I detect the most important points from the image such as corners using the cvGoodFeaturesToTrack function.

In the second image the same points were tracked using the cvCalcOpticalFlowPyrLK function.
