Abstract:
Ê
Ê
Partial differential equations (PDEs) are widely used in Visual Computing fields to model geometric objects, simulate natural phenomena, formulate physical laws, etc. To make full use of the advantages of PDE techniques for geometric modeling, I present a PDE-based modeling system employing different types of PDEs for various shape representation formats including parametric surfaces and solids, polygonal meshes, and implicit volumetric models. The system offers a comprehensive set of shape modeling functionalities such as shape design, damaged data recovery, model reconstruction, arbitrary shape blending, manipulation and deformation, as well as shape abstraction. In particular, the PDE-based modeling framework provides a user-friendly environment that allow users to design geometric shapes using sketches, reconstruct objects from scattered data points, recover missing information from damaged volumetric datasets, deform geometric objects by direct manipulation toolkits, offer smooth transitions between blending objects, and approximate medial axes or skeletons for shape analysis purpose. The variety of shape representations accepted by the system also facilitates data exchange and communication among different models. In addition, PDE-based techniques can also be used in medical image processing for segmentation, animation, registration, etc. Part of my current research is focusing on applying PDEs with statistical functions for image smoothing filters and considering partial differential properties for medical image registration.
