&lt;br /&gt;
This extension provides an example on how to build and run against the OpenCV package provided by the &lt;br /&gt;
[[Documentation/{{documentation/version}}/Extensions/SlicerOpenCV | SlicerOpenCV extension]]. [http://opencv.org/ OpenCV] (Open Source Computer Vision Library) is an open source computer vision and machine learning software library.&lt;br /&gt;
&lt;br /&gt;
This extension includes a C++ CLI module that loads, operates on, and saves PNG images.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;!-- ---------------------------- --&amp;gt;&lt;br /&gt;
{{documentation/{{documentation/version}}/module-section|Use Cases}}&lt;br /&gt;
&lt;br /&gt;
* This module can be used as a template by extension developers who wish to use the algorithms provided by [http://opencv.org OpenCV].&lt;br /&gt;
&lt;br /&gt;

&amp;lt;!-- ---------------------------- --&amp;gt;&lt;br /&gt;
{{documentation/{{documentation/version}}/module-section|Panels and their use}}&lt;br /&gt;
&lt;br /&gt;
The ExampleOpenCV extension provides the  [[Documentation/{{documentation/version}}/Extensions/BlendVectorVolumes|Blend Vector Volumes]] CLI as a stand alone module, but the extension does not provide an overall GUI.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;!-- ---------------------------- --&amp;gt;&lt;br /&gt;
{{documentation/{{documentation/version}}/module-section|Similar Modules}}&lt;br /&gt;
&lt;br /&gt;
The [https://github.com/SBU-BMI/SlicerPathology Slicer Pathology] extension also uses the [[Documentation/{{documentation/version}}/Extensions/SlicerOpenCV | SlicerOpenCV extension]].&lt;br /&gt;

&lt;br /&gt;
Use this extension as a template on how to include OpenCV provided by the SlicerOpenCV module.&lt;br /&gt;
&lt;br /&gt;
In your extension's top level CMakeList.txt:&lt;br /&gt;
* Specify that it depends on SlicerOpenCV:&lt;br /&gt;
  set(EXTENSION_DEPENDS &amp;quot;SlicerOpenCV&amp;quot;)&lt;br /&gt;
* Include the SlicerOpenCV extension by including this line after the find_package for Slicer:&lt;br /&gt;
  find_package(SlicerOpenCV REQUIRED)&lt;br /&gt;
* If you're building from a locally built version of SlicerOpenCV, SlicerOpenCV_DIR is set to the inner-build sub-directory of the SlicerOpenCV build directory.&lt;br /&gt;
&lt;br /&gt;
In your extension's module CMakeLists.txt file:&lt;br /&gt;
* Define OpenCV_DIR by finding the package that SlicerOpenCV provided:&lt;br /&gt;
  find_package(OpenCV 3.1 REQUIRED)&lt;br /&gt;
* The header include path is defined as:&lt;br /&gt;
  get_filename_component(OpenCV_INCLUDE_DIR ${OpenCV_DIR}/../../include ABSOLUTE)&lt;br /&gt;
* Add ${OpenCV_INCLUDE_DIR} to the MODULE_INCLUDE_DIRECTORIES list&lt;br /&gt;
* Link against the OpenCV libraries by adding ${OpenCV_LIBS} to the MODULE_TARGET_LIBRARIES&lt;br /&gt;
