Supplementary Material for: Active Pictorial Structures

In the following sections, we provide additional material for the paper “Active Pictorial Structures”. Section 1 explains in more detail the differences between the proposed Active Pictorial Structures (APS) and Pictorial Structures (PS). Section 2 presents the proofs about the structure of the precision matrices of the Gaussian Markov Random Filed (GMRF) (Eqs. 10 and 12 of the main paper). Section 3 gives an analysis about the forward Gauss-Newton optimization of APS and shows that the inverse technique with fixed Jacobian and Hessian, which is used in the main paper, is much faster. Finally, Sec. 4 shows additional experimental results and conducts new experiments on different objects (human eyes and cars). An open-source implementation of APS is available within the Menpo Project [1] in http://www.menpo.org/.
