The general area of the 3D-SAM team will be to advance methodologies and algorithms for modeling and analyzing static and dynamic 3D shapes. Specifically, we will develop tools and methods for :
Shape analysis of surfaces: a large number of applications involve the statistical analysis and modeling of 3D objects that can be represented as surfaces in 3D. The difficulty in analyzing shapes of such objects comes from noisy and missing data, variability in pose and articulation, arbitrary mesh parametrizations during data collection, and shape variability within and across shape classes. These issues require metrics, representations and statistics that should have certain invariances and robustness to the aforementioned variabilities.
Modeling dynamics of shape variation in Videos: many human-machine interaction environments are characterized by temporally-evolving shapes of 3D objects. Examples include gesture and action recognition using full body scans, emotion classification using facial data and so on. It is critical to identify precise mathematical representations of underlying shapes, and then impose efficient dynamical models on representation spaces that capture the essential variability in shape evolution.
