Simple demo program for color based tracking

Simple script to read a video file and track a single red marker in 2D using hue and saturation.

Simple script to read a video file and track a single red marker in 2D using the hue and saturation values. The largest red blob is detected and the mean co-ordinate position of this blob is tracked. This code does not have any tracking built-in: it treats each frame independently.

This assumes that the video is a constant frame rate video. The resulting co-ordinate time series are stored in the variables: t, Xc and Yc.
