Deformable and Functional Models

This article summarizes most of the material on deformable and functional models that the author covered in an invited plenary lecture presented at the 2009 VIPIMAGE Conference. Following the organization of the presentation, the first part of the article reviews deformable models, particularly, active contours and surfaces, topologically-adaptive active contours and surfaces, and deformable organisms, focusing on their applications in medical image analysis, while the second part of the article reviews functional models, particularly realistic biomechanical models of the human face and body.
