Module Description
This is a CLI module that depends on the SlicerOpenCV extension, providing a way to blend two vector volumes together. It uses the OpenCV function addWeighted.
Use Cases
When loading in RGB files, they are loaded as vector volumes in Slicer. Use this module to blend them together if they have the same dimensions.

To depend on the OpenCV provided by the SlicerOpenCV extension, 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
The images are read in using the opencv imread method. The blending is done by the opencv addWeighted function, and the output is written using imwrite.
