After going through the [**Camera Streamer Tutorial**](https://amiga.farm-ng.com/docs/tutorials/camera_streamer/camera-streamer-overview), you may still be wondering how you can add OpenCV to your version of the [**camera-streamer**](https://github.com/farm-ng/camera-streamer) app to perform image processing.

Well just like `PyTurboJPEG` was added to the [`setup.cfg`](https://github.com/farm-ng/camera-streamer/blob/main/setup.cfg), you can add `opencv-python` under the `install_requires` section.

Then it’s as simple as importing in your python file with `import cv2` and using the library!

Checkout this simple example showing how this is done:

[**Demonstrate adding opencv to camera streamer example**](https://github.com/farm-ng/camera-streamer/pull/6/files)

This example uses OpenCV to draw a red circle in the center of the image streams, but we’re sure you’ll use OpenCV for something much more interesting!
