More path detection updates & videos

Following a suggestion by Nir I changed the algorithm to work using offline sampling for the creation of the road and non-road models, I built a small application that allows a user to highlight areas that should be included in the road/non-road model and used it to train the GMM on some path images I've taken (the rest of the algorithm is the same, read the previous post for details).
This has improved the performance of the algorithm and helped reduce running time a little bit, but the algorithm still has difficulties with some scenes, mainly when shadows are involved.
I'm posting 2 nice videos that show the algorithm's abilities :)

1) Detecting an obstacle

2) Moving between two types of paths
