Landmarks or features are usually found using SURf, SIFT, or ORB. The Hungarian method is a combinatorial optimization algorithm that solves the assignment problem in polynomial time and which anticipated later primal-dual methods. Once the detection locates the face, the next step in the example identifies feature points that can be reliably tracked.
