Abstract:

This project investigated sampling theoretic issues that arise in visualization of 3-D e.g., in simulation or biomedical datasets. As sampling and reconstruction are key elements in the visualization pipeline, their mathematical modeling and analysis are foundational to reliability of the resulting visualizations. An important achievement of this investigation is establishing the superiority of optimal lattices for reconstruction of scattered data. These lattices are observed in nature as crystallographic structures e.g., body centered cubic and face centered cubic lattices, as well as biological vision systems e.g., hexagonal lattice. While the sampling theoretic advantages of optimal lattices have been established, practical tools e.g., filtering, interpolation, wavelet analysis, signal reconstruction, regularization methods for exploiting these advantages have been unavailable to practitioners.
