Integrating with OpenCV

OpenCV is a very powerful open-source library for computer vision. The library is written in C++ so it can be easily integrated in your Cinder application. There is a very useful OpenCV Cinder block provided within Cinder package available at the GitHub repository (https://github.com/cinder/Cinder-OpenCV).

Getting ready

Make sure you have Xcode up and running with a Cinder project opened.

1. Add a new group to our Xcode project root and name it Blocks. Next, drag the opencv folder inside the Blocks group. Be sure to select the Create groups for any added folders radio button, as shown in the following screenshot:

   

2. You will need only the include folder inside the opencv folder in your project structure, so delete any reference to others. The final project structure should look like the following...
