Workshop Programme

Invited talk by Tim Cootes

Image Segmentation using Statistical Shape and Appearance Models

Many objects of interest in images can be represented as deformed versions of some average structure - for instance faces, bones and many organs in medical images. This talk will describe methods of constructing statistical models of the variation in shape and appearance of such objects from annotated sets of examples. Tim Cootes will give an overview of efficient regression-based techniques for matching such models to new images, including Active Appearance Models and a powerful approach which uses Random Forest regression to vote for the most likely position of each model point. The various methods will be demonstrated on a range of applications, including facial image interpretation and medical image analysis in 2D and 3D images.
