1. GPU Brainstorming What Classes to focus on

2. Top Priorities Level Sets – (1) ParallelSparseFieldSolver (look at link from Paul) – (?) NarrowBandLevelSet – Must be Streamable Registration – Image Metrics (13) Mattes (may not be a good candidate), Mean – Resampling (6) Bspline Transform (?) (5) WindowingSinc Interpolator (only for final resampling) FiniteDifferenceFilter – (4) Anisotropic Diffusion (…it must stream…) – (2) Demons – (7) Level Sets (shape detection, geodesic active contours)

3. Top Priorities (10) Geodesic Morphology – Richard Beare (11) Region Growing – ConfidenceConnected (FloodFill iterator) (5) FFT Transform (…if there is already a lib out there.. Apple ?) (7) BinaryFunctorImageFilter (7) UnaryFunctorFilter (7) ConvolutionFilters (15) Iterative Conditional Modes (statistics) (7) Basic filters (Gaussian, Median)

4. Criteria Focus on algorithms that take several minutes (instead of making interactive the ones that take seconds). Scalability ? linear with number of cores ? Intraoperative imaging registration

5. Good Targets 3D Mattes Mutual Information, Deformable Registration (with Bsplines) Rigid Registration Mutual Information (Greg Sharp) – (histogram based)
