You will learn how to setup OpenCV on your computer
Here you will learn the about the basic building blocks of this library. A must read for understanding how to manipulate the images on a pixel level.
In this section you will learn about the image processing (manipulation) functions inside OpenCV.
This section contains valuable tutorials on how to use the built-in graphical user interface of the library.
These tutorials show how to read and write images using imgcodecs module.
These tutorials show how to read and write videos using videio module.
Although most of our images are in a 2D format they do come from a 3D world. Here you will learn how to find out 3D world information from 2D images.
Learn about how to use the feature points detectors, descriptors and matching framework found inside OpenCV.
Here you will find algorithms usable on your video streams like motion extraction, feature tracking and foreground extractions.
