OpenCV is an open source toolbox that consists of different software tools developed for image processing. OpenCV is a cross-platform toolbox that has been developed with support for different operating systems. Because OpenCV is available under an open source license, researchers across the world have contributed to its growth by developing tools and techniques. This has made developing applications with relative ease. Some applications of OpenCV include face recognition and license plate recognition.

Due to its limited processing power, it can take several hours to complete the installation of the framework. It took us approximately 10 hours at our end.

We followed the instructions to install OpenCV on the Raspberry Pi Zero from http://www.pyimagesearch.com/2015/10/26/how-to-install-opencv-3-on-raspbian-jessie/.We specifically followed the instructions to install OpenCV with Python 3.x bindings and verified the installation process. It took us approximately 10 hours to finish installing OpenCV on the Raspberry Pi Zero. We are not repeating the instructions in the interest of not reinventing the wheel.
