Module Description

This is a CLI module that depends on the SlicerOpenCV extension, providing a way to blend two vector volumes together.

Use Cases

When loading in RGB files, they are loaded as vector volumes in Slicer. Use this module to blend them together.

Tutorials

Panels and their use

  • Alpha: A double value between 0.0 and 1.0 that gives the weight of the first input image in the resulting blend.
  • Gamma: A double value that is added to the weighted blend, used to increase or decrease intensity.
  • First Input Volume: First input vector volume
  • Second Input Volume: Second input vector volume
  • Output Volume: Output vector volume, holding the blending of the two inputs

Information for Developers


To depend on the OpenCV provided by SlicerOpenCV, in the CLI's 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

OpenCVExample provides some more information about writing an extension that includes modules that depend on OpenCV
