GPU Brainstorming

What Classes to focus on


Top priorities
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)


Top priorities1
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)


Criteria
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


Good targets
Good Targets

  • 3D Mattes Mutual Information, Deformable Registration (with Bsplines)

  • Rigid Registration

  • Mutual Information (Greg Sharp)

    • (histogram based)
