Welcome back to Pattern Recognition. Today we want to have the last video of our lecture and we actually want to look into an application of Adaboost and this is going to be the Viola-Jones algorithm that was published in 2001.

So the Viola-Jones algorithm is really famous because it solved the face detection problem. It’s using integral images for the feature computation and it uses Adaboost for the actual classification. Then this is building a classifier cascade for the fast rejection of…
