Output Image after edge detection.


Key Investigators

  • MIT: Elliot Uvero
  • BWH: Lauren O'Donnell
  • Kitware: Luis Ibanez
Working hard on ITK and Slicer3

Objective

Enable edge detection of images in Slicer3.

Approach, Plan

Create a Slicer3 CLP module for edge detection of images, using ITK filters.

Progress

A CLP module has been developed in Slicer3. With the great help of Luis, the documentation and error checking of the ITK ZeroCrossingEdgeDetectionFilter were improved.



Conclusions and Findings

  • Concept checking should be set to ON in CMake when ITK is configured.
    • With it off (default), there was no check that input/output image is the same type for the itkZeroCrossingEdgeDetectionFilter.
  • Currently the itkZeroCrossingEdgeDetectionFilter functions appears to function correctly with float input. Short input produces different edge output.
