Module Description

Use Cases

This extension provides an example on how to build and run against the OpenCV package provided by the SlicerOpenCV extension.

Panels and their use

The ExampleOpenCV extension provides the Blend Vector Volumes CLI as a stand alone module, but the extension does not provide an overall GUI.

Similar Modules

The Slicer Pathology extension also uses the SlicerOpenCV extension

Information for Developers

Use this extension as a template on how to include OpenCV provided by the SlicerOpenCV module:

• In your extension's top level CMakeList.txt:
  • Specify that it depends on SlicerOpenCV:

 set(EXTENSION_DEPENDS "SlicerOpenCV")

• • Include the SlicerOpenCV extension by including this line after the find_package for Slicer:

 find_package(SlicerOpenCV REQUIRED)

• In your extension's module CMakeLists.txt file:
  • Define OpenCV_DIR by finding the package that SlicerOpenCV provided:

 find_package(OpenCV 3.1 REQUIRED)

• • The header include path is defined as:

 get_filename_component(OpenCV_INCLUDE_DIR ${OpenCV_DIR}/../../include ABSOLUTE)

• • Add ${OpenCV_INCLUDE_DIR} to the MODULE_INCLUDE_DIRECTORIES list
  • Link against the OpenCV libraries by adding ${OpenCV_LIBS} to the MODULE_TARGET_LIBRARIES
