Interactive Processing of Level Sets  Aaron Lefohn and Ross Whitaker

    The goal of this project is to accelerate the level set deformable surface methods to interactive rates by mapping both the computation and visualization to programmable graphics hardware (GPU).

1. A 3D GPU-Based Level-Set Solver with Curvature Flow:

We have implemented a 3D level set solver running on the ATI Radeon 8500 GPU. In addition to running in 3D, the solver computes the second-order, mean curvature speed term in spite of the 8-bit memory limitations. The GPU-baed solver runs at 1x-2x faster than a higly-optimized sparse-grid CPU-based solver. We demonstrate the solver segmenting the cerebral cortex surface from a 256 x 256 x 175 MRI volume.
