Project Goals:

With the popularity of real-time 3D/4D data capturing capabilities, there is an emerging need to compute the deformable models over the networks. Traditional model-driven deformable models have their bottlenecks since the spatial information for large-scale datasets cannot be efficiently solved and adaptively minimized over different network conditions. This project centers on the concept of spectrum-driven deformable models. Analogous to Fourier analysis being applied to image processing, the spectral deformable models employ manifold harmonics to efficiently and effectively perform segmentation, registration, physics-based simulation, compression, and streaming of 3D deformable surfaces and volumes. In this project, manifold harmonics are used to transform arbitrary scanned datasets into a reduced diffusion subspace, in which real-time segmentation, registration, and physics-based simulation can be performed. Besides the stretching deformations, the rotational and tensor fields are encoded with manifold harmonics, which provides a "spectral multiresolution" structure to compress and stream deformable models over different network conditions.
