Talk : Image Interpretation using Statistical Shape 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. The talk will include an overview of "Groupwise Registration" algorithms, which can automatically compute correspondences across large sets of 2D and 3D images. Such methods can be used to automatically construct shape and appearance models with minimal manual intervention. I will also describe methods of initialising registration using automatically constructed part+geometry models, which can significantly improve overall robustness on challenging registration problems. I will give an overview of efficient regression-based techniques for matching shape/appearance models to new images. I will focus on two approaches.
  1. Active Appearance Models and their variants, in which model parameters are incrementally updated using estimates predicted from image information sampled from regions defined by the current points.
  2. A powerful approach which uses Random Forest regression to vote for the most likely position of each model point, then finds the shape which gives the best overall response.
  3. This has been found to give robust results on many different applications.

Talk : 3D Morphable Face Models

The analysis of face images has many aspects reaching from face identification to social judgement or to medical questions. In our research we aim on a single unifying approach for these tasks. The core of our approach is an analysis by synthesis loop using a 3D morphable face model for reconstructing the image to analyse. Based on various face image analysis tasks I will demonstrate the advantage of generative models and discuss also current limitations of our model and approach.

Talk : Statistics of Shape on Manifolds: Methods and Comparison Methods

The geometry of an object modulo translation and possibly rotation is best understood as a point on an abstract manifold with significant curvature. Even zero-order geometry, i.e., a list of positions, has this property. Higher order geometry involving local properties such as directions or curvatures or non-local properties such as cross-object relations adds curving dimensions to the abstract manifold. The presentation will survey object geometry models (OM) to support shape statistics, as well as techniques for doing shape statistics on curved manifolds (ST). Because different ST,OM pairs (STOMPs) have been proposed, methods to compare STOMPs are needed. These STOMP comparison methods will also be discussed.

Talk : Shape Models in Medical Device Development

The introduction of statistical shape models into industrial applications has been slower than expected considering their popularity in the research community. Our speakers are involved in bringing shape model-related medical devices to market and will share their experience with shape modeling in an industrial environment. This includes practical applications from radiotherapy planning and orthopedic implant development. A large part of the talk will focus on the challenges of showing clinical effectiveness of solutions and other aspects of the highly regulated medical device industry. These practical challenges are mostly not addressed in current research, even if it is medically motivated. The speakers hope to raise awareness and invite researchers to focus on these issues in order to help the translation of shape models to practice, so we all can see patients benefit from this exciting technology.
