BEFORE!

Output Image after edge detection.

Key Investigators

• MIT: Elliot Uvero
• BWH: Lauren O'Donnell
• Kitware: Luis Ibanez

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.
  • When off (default) there is no check that input/output image is the same type for the itkZeroCrossingEdgeDetectionFilter.
• Currently the itkZeroCrossingEdgeDetectionFilter appears to function correctly with float and double input.
  • Short input produces different edge output.
