A primary goal of statistical shape analysis is to describe the variability of a population of geometric objects. A standard technique for computing such descriptions is principal component analysis.â€¦ (More)

Principal component analysis has proven to be useful for understanding geometric variability in populations of parameterized objects. The statistical framework is well understood when the parametersâ€¦ (More)

M-reps (formerly called DSLs) are a multiscale medial means for modeling and rendering 3D solid geometry. They are particularly well suited to model anatomic objects and in particular to captureâ€¦ (More)

The Gaussian distribution is the basis for many methods used in the statistical analysis of shape. One such method is principal component analysis, which has proven to be a powerful technique forâ€¦ (More)

We present a methodology for estimating the probability of multi-object anatomic complexes that reflects both the individual objectsâ€™ variability and the variability of the inter-relationshipsâ€¦ (More)

We use multifigure m-reps to represent anatomical objects, such as human livers, with named components. Each component is represented as a single figure m-rep. These figures of the object areâ€¦ (More)

The shape of a population of geometric entities is characterized by both the common geometry of the population and the variability among instances. In the deformable model approach, it is describedâ€¦ (More)

In many areas of computer vision, such as multiscale analysis and shape description, an image or surface is smoothed by a nonlinear parabolic partial differential equation to eliminate noise and toâ€¦ (More)

The geometric conformation of an object complex is usually described by certain geometric features, which are most intuitive and provide locality if each is chosen to be at a restricted range ofâ€¦ (More)
