Classes to implement Felzenszwalb and Huttenlocher's elegant dynamic programming style approach to matching object part models to new images. (Efficient Pictoral Structure Matching).

A model consists of a set of feature detectors together with a tree structure describing the spacial relationships between the model points. The algorithm uses the vil_quadratic_distance_function applied to the feature response images to significantly reduce the complexity of search, leading to a fast method of locating the globally optimal positions of all model points.
