11Project Objective

To use implicit models to capture the variation of shapes (such as skulls)  with variable topology, and then use the model to compare, repair, and complete partial digitized objects.

Operations/ProblemsAreasAddressed

Forensics: Forensic estimation from skulls, matching mandibles with craniums or creating a plausible mandible. Medicine / Plastic Surgery: Estimating the shape of missing or damaged anatomy. Spatial Databases: Comparing objects with different topology, analyzing class characteristics of objects to allow meaningful comparisons.

Technology and Impact

New algorithms: for fitting sparse and compact implicit models to laser scanned or CT data; for estimating the shapes of missing or damages parts of objects; for registering surfaces and finding landmarks. Enabling Technologies: For forensic estimation from skulls, for facial animation,  for plastic surgery planning, for generating plausible characters in games. Information Analysis: Enables new scientific explorations especially in Anthropology and Anatomy by characterizing morphology of 3D specimens even when landmark points used in traditional analyses are ill-defined.
