ABSTRACT

Active Appearance Models

Tim Cootes, University of Manchester

An Appearance Model contains statistical models of both the shape and the texture of a structure in an image. They can be generated from training sets of images labelled with the positions of landmark points around the structures of interests. They can be used to reconstruct synthetic images of the structures. By varying the parameters between limits learnt from the training set new examples, similar to those in the training set, can be generated. The Active Appearance Model algorithm allows us to match a model to a new image rapidly. The method works by using a vector of differences between the current model appearance and the target image appearance to drive the model parameters toward a better match.

In this talk I will describe the models and search algorithm, giving examples of its application to images of faces and medical images.
