Introduction

What is OpenCV?

OpenCV (Open Source Computer Vision) is a library of programming functions mainly aimed at real time computer vision.

Example applications of the OpenCV library are Human-Computer Interaction (HCI); Object Identification, Segmentation and Recognition; Face Recognition; Gesture Recognition; Motion Tracking, Ego Motion, Motion Understanding; Structure From Motion (SFM); Stereo and Multi-Camera Calibration and Depth Computation; Mobile Robotics.

OpenCV book

• Learning OpenCV: Computer Vision with the OpenCV Library

  • by Gary Bradski and Adrian Kaehler, O'Reilly Press, October, 2008.

• Japanese Translation: 詳解 OpenCV (単行本（ソフトカバー）)

• Chinese Translation: 学习OpenCV（中文版）(预订中,估价) [新品]

• It is a textbook that covers

  • Computer vision in general, intuition to the algorithms and theory
  • User's guide to OpenCV with pragmatic working examples
  • Function specs and tuning intuitions

How do I Download OpenCV?

• The current release is: 2.0.0 Linux/Mac, Windows.

• To get the latest SVN code, use: svn co https://code.ros.org/svn/opencv/trunk/opencv To build, see the Install Guide below.

• Next OpenCV Official Release: 2.1.0 is due March 31st, 2010.

Release Numbering Philosophy:

• The convention OpenCV follows for release numbering is:

• We will try to loosely follow Linux minor number even-odd release conventions where the API for new functionality is less stable/documented on odd minor numbers and more stable/documented on the even numbers.

Installing OpenCV

1. Installing OpenCV on Linux, Windows or MacOS

Getting Started with OpenCV

1. Using Visual C++ and OpenCV

2. Using Eclipse IDE and OpenCV

3. Using C++ Builder IDE and OpenCV

4. Using DevCpp IDE and OpenCV

5. C/C++ interpreter Ch and OpenCV.

6. How do I compile OpenCV and OpenCV programs in Linux? - Also see notes in the Linux section of OS Specific Stuff below

7. Using OpenCV with Visual C++ and Microsoft's DirectShow

8. How do I compile OpenCV and OpenCV programs on Mac OS/X?

Frequently Asked Questions

Problem Specific Frequently Asked Questions

1. Beginners/Newbie FAQ's (how to access a pixel etc.)

2. Is there a user group or forum for OpenCV? Yes: OpenCV Yahoo Group

3. How to use OpenCV to capture and display images from a camera

4. Which video file formats can I use with OpenCV?

5. How do I use OpenCV to Detect Faces?

6. Using OpenCV for Face Recognition

7. How to use OpenCV to Detect Objects?

8. How to use the OpenCV Blob Extraction Library

9. How do I correctly refresh my HighGUI application?

10. Where to download DirectShow?

11. How to Display more than one image in a single window?

12. CodingStyleGuide

13. VideoSurveillance

14. Where do I report a bug or request new features or raise documentation issues?

    • In general, you can go to https://code.ros.org/trac/opencv/wiki/

      • You will first need to register at https://code.ros.org/gf/ (This is only for spam control, your name is not given out). Then:

      • Click on "new ticket" to file a new bug report or feature request, or submit a patch.
      • Click on "view tickets" or "search" to look for existing tickets - probably your problem is already known or even fixed in the latest SVN version.

    • Bug Notes:

      • Do the work: Submit as much information as you can (what OS, what compiler, what OpenCV version).
      • To help rapidly fix the bug, it is preferable to also attach a short program plus data that reproduces the problem.
      • You can and should submit bugs for documentation. Again, be specific (C, C++, Python). What exactly was missing, confusing or wrong.
        • If you know how the documentation should be fixed, submit that too.
