Modeling the Remaining Flexibility of Partially Fixed Statistical Shape Models

Abstract : Statistical shape models are widely used to model the variability of biological shapes. They can be used to reconstruct missing information given partial or noisy data. In case of partial data, many different reconstructions are possible, and one is not only interested in a plausible reconstruction but also the remaining flexibility within the model and the reliability of the reconstruction. We present a method to model the remaining flexibility when some part of a statistical shape model is fixed. Using such a flexibility model, we can give answers to questions like: Does one half of a human femur bone determine the other half? or How much is the shape of a face determined by its contour?
