Key Investigators

Objective	Approach and Plan	Progress and Next Steps
Add an extension to the Slicer extension repository that provides OpenCV as a library	Create CMake files to check out and build OpenCV as an external project Create CMake files to check out and build the ITK OpenCV bridge as an external project Provide examples on how to use OpenCV from Slicer	SlicerOpenCV CMake file created to build OpenCV Enabling the ITK OpenCV Bridge: The Slicer version of ITK needed changes from this patch in order to be able to build with the module enabled: COMP: simplify ITKVideoBridgeOpenCV dependency Building the bridge outside of the source referred to ITK mailing list posts: Building ITK SNAP outside of the application New post: Building BridgeOpenCV outside of ITK Consulted with Jim on best practices for building ITK and linking to libs and include dirs Worked with JC to craft CMake files to build the bridge Pointed to relevant blog post: Build ITK Modules Outside the Main Repository Matt McCormick proposed a patch to ITK to enable building the bridge outside of ITK: Allow ITKVideoBridgeOpenCV to be built externally. Extension topic branch builds against the ITK trunk version of the bridge with Matt's patch, and loads into Slicer: Enable-ITK-BridgeOpenCV To do: patch Slicer's branch of ITK set up dependency with the digital pathology module so that it uses this version of OpenCV
