OpenCV Tutorials

The following links describe a set of basic OpenCV tutorials. All the source code mentioned here is provide as part of the OpenCV regular releases, so check before you start copy & pasting the code. The list of tutorials below is automatically generated from reST files located in our GIT repository.

As always, we would be happy to hear your comments and receive your contributions on any tutorial.

• Introduction to OpenCV

  You will learn how to setup OpenCV on your computer!

• core module. The Core Functionality

  Here you will learn the about the basic building blocks of the library. A must read and know for understanding how to manipulate the images on a pixel level.

• imgproc module. Image Processing

  In this section you will learn about the image processing (manipulation) functions inside OpenCV.

• highgui module. High Level GUI and Media

  This section contains valuable tutorials about how to read/save your image/video files and how to use the built-in graphical user interface of the library.

• calib3d module. Camera calibration and 3D reconstruction

  Although we got most of our images in a 2D format they do come from a 3D world. Here you will learn how to find out from the 2D images information about the 3D world.

• feature2d module. 2D Features framework

  Learn about how to use the feature points detectors, descriptors and matching framework found inside OpenCV.

• video module. Video analysis

  Look here in order to find use on your video stream algoritms like: motion extraction, feature tracking and foreground extractions.

• objdetect module. Object Detection

  Ever wondered how your digital camera detects peoples and faces? Look here to find out!

• ml module. Machine Learning

  Use the powerfull machine learning classes for statistical classification, regression and clustering of data.

• gpu module. GPU-Accelerated Computer Vision

  Squeeze out every little computation power from your system by using the power of your video card to run the OpenCV algorithms.

• contrib module. The additional contributions made available !

  Discover additional contribution to OpenCV.

• OpenCV iOS

  Run OpenCV and your vision apps on an iDevice

• General tutorials

  These tutorials are the bottom of the iceberg as they link together multiple of the modules presented above in order to solve complex problems.
