In this Lab we like you to write an efficient program to track a region in a sequence of images. It should be useful to use a convex hull of the cloud of points to define the enveloping region. Here you can find some ideas on how to use such a blob for tracking.

What happens if such a blob becomes partially occluded ?

Up to now, we have already compute a color region of interest and if necesary we can find some geometric features. We are ready to start using a sequence of images with the main objective of tracking some moving object. At each frame we have to determine where the object is moving to or -in the case of a mounted camera - which is the motion the robot have done.

In this Lab we like you to write an efficient program to track a region in a sequence of images. Make use of the a convex hull to define the region envelope and by means of conecting lines create an envelope of such a region. Your algorithm needs to deal with some deformations of such an initial Blob.
