Active Appearance Models (AAMs)

A fast but exact version of the Simultaneous Inverse Compositional Algorithm (SIC)

Source code for training an Active Appearance Model (AAM) and fitting using the Fast Simultaneous Inverse Compositional Algorithm (Fast-SIC), described in

[1] G. Tzimiropoulos, and M. Pantic, "Optimization problems for fast AAM fitting in-the-wild," ICCV 2013

The code is based on the Inverse Compositional framework of

[2] I. Matthews and S. Baker, “Active Appearance Models Revisited,” IJCV, 60(2), pp. 135–164, 2004.

The provided code implements Fast-SIC, a fast but exact version of the Simultaneous Inverse Compositional Algorithm (SIC). You can use it to fit an AAM to unconstrained (in-the-wild) images. Please see [1] for more details.
