Active Appearance Model¶
AAM is a generative model that consists of a statistical parametric model of the shape and the appearance of an object. MenpoFit has several AAMs which differ in the manner that they compute the warp (thus represent the appearance features).
An AAM can be optimised either in a gradient descent manner (Lucas-Kanade) or using cascaded regression (Supervised Descent).
