Definition

An active appearance model (AAM) is a statistical generative model of deformable objects, which simultaneously models shape and appearance variation. The term AAM often refers to not only a model but also a fitting algorithm associated with the model.

Background

When a deformable object changes its shape, the deformation affects both the 2D shape and appearance (texture) on the captured images of the object. Modeling such shape and appearance variation enables us not only to synthesize photo-realistic images but also to interpret images (interpretation by synthesis). That is, once a parametric generative model is fit to an object in an image, the model parameters “explain” the object in terms of its position, orientation, scale, shape, and appearance. Therefore, a variety of parametric shape and appearance models were...
