 | Hansen, Charles D.; Whitaker, Ross T. | Interactive deformation and visualization of level set surfaces using graphics hardware | Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization for applications such as segmentation, surface processing, and surface reconstruction. Their usefulness has been limited, however, by their high computational cost and and reliance on sig... | Deformation; Level sets; Deformable models; Image segmentation; Volume visualization; GPU; Streaming computation; Isosurfaces | 2003 |

 | Lefohn, Aaron; Cates, Joshua E.; Whitaker, Ross T. | Interactive, GPU-based level sets for 3D brain tumor segmentation | While level sets have demonstrated a great potential for 3D medical image seg- mentation, their usefulness has been limited by two problems. First, 3D level sets are relatively slow to compute. Second, their formulation usually entails several free parameters which can be very difficult to correc... | Level sets; Medical imaging; 3D brain tumor segmentation | 2003-04-16 |

 | Hansen, Charles D. | Wavelet representation of contour sets | We present a new wavelet compression and multiresolution modeling approach for sets of contours (level sets). In contrast to previous wavelet schemes, our algorithm creates a parametrization of a scalar field induced by its contours and compactly stores this parametrization rather than function valu... | Contours; Geometry compression; Isosurfaces; Level sets; Multiresolution methods; Wavelets | 2001 |
