Top 8 Resources To Learn OpenCV For Beginners

OpenCV or Open-Source Computer Vision Library is one of the popular machine learning libraries, which is built to deliver a common infrastructure for Computer Vision applications. With the increasing number of computer vision applications in our day-to-day life, this library has been gaining much prominence among organisations and academia. 

Emerged from an Intel Research initiative, OpenCV library is a cross-platform and open-source library that portrays a significant role when it comes to the growth of computer vision due to several intuitive factors. Below, we have curated top eight resources for beginners, in no particular order, to learn OpenCV.

OpenCV Tutorials

The OpenCV Tutorials is provided in the official documentation by the developers of OpenCV. In this tutorial, you will learn how to set up OpenCV on your computer, learn about the basic building blocks of this library, image processing (manipulation), etc. Along with that, you will also learn how to use the built-in graphical user interface of the library, how to read and write images using imgcodecs module, how to use the feature points detectors, descriptors and matching framework found inside OpenCV and more.
