OpenCL Implementation of GrowCut running in the Editor Module. (See demo video)
Input into the ITK's morphological watershed from markers.
Resulting segmentation by morphological watershed from markers.
Key Investigators
- Isomics: Steve Pieper
- GI: Jim Miller
- BWH: Yi Gao
- GaTech: Ivan Kolasev
- NIH: Brad Lowekamp (C)
Objective
Provide a framework for Streered Segmentation in the Editor Module.
Approach, Plan
An example implementation of GrowCut has been implemented as a test.
During project week we would like to:
- Discuss the implementation with potential users and developers in order to generalize the approach and improve the interface.
- Discuss other algorithms suitable for this apuproach
- Possibly test this module on multiple CPU/GPU options to compare performance. (may be tricking since installation is not automated)
- Identify OpenCL/GPU programming experts to help evaluate and improve the implementation.
See the repository for more information: https://github.com/pieper/SlicerCL
(Note that use of this module requires installation of PyOpenCL into the slicer python build tree - see this example script. Also note that the current implementation depends on some changes to the Editor module that only exist in a threeDEditor branch.)
Progress
- Topic was generalized to include editor effects based on ITK and VTK
- SimpleITK tools (Brad)
- Marker based watersheds [1]
- Binary watershed to split object [1]
- DoubleThresholding
- Current prototypes are on github.
- Porting of CLI tools to run as steered segmenters (Yi, Ivan)
- SimpleITK tools (Brad)
- Productive discussions with other developers about future strategies and uses of OpenCL (pyopencl)
