Project Description
Video Demo 1: Femur Epyphisis (youtube link)
Video Demo 2: Brain White + Grey matter (youtube link)
Objective
- Improve Slicer interactive segmentation workflow
- Add useful integral-like functionality to Slicer that have been useful in external matlab/c++
- Port new theoretical developments into Slicer segmentation tool
- Add coupled interactive level sets, use coupling matrix that pivots on the "active" surface
Approach, Plan
- Verify lack of current integral functions in Slicer
- Integrate bug fixes from Ivan Kolesov and Karl Fritscher
- Try to separate CLI-like functions in interactive segmentation tool into separate own modules
Progress
- bugfix for vanishing contour when image is ~constant or very noisy
- generate and some synthetic data to stress the segmentor
- gained some better understanding of python modules, planning on having kslice get instantiated from python script, although this might be limited to linux/mac.
- see video demo 1 above; very tight coupling with QT, VTK, user feedback/display.
- with integration functions, technically Slicer python + numpy can do this but requires a programmer with python knowledge. Prototyped a small parser for matlab-like syntax to be applied to Volumes in Slicer.
