OpenCV - Computer vision from Intel

Sunday, 08 May 2005 19:55
OpenCV is an open source vision library suitable for computer vision applications. An added benefit is that the library makes use of Intel's integrated performance primitives so it's optimized for Intel hardware. :)

I've used OpenCV for quite a few projects and I've been happy with the results. The api takes some time to get used to...but it is well worth it.

Also, it surprised me to see that 'opencv' is one of the more popular pages on my website. I'm not sure why this is. I can't say that this page the most content in the world. Maybe, it is helping people find the few opencv tutorials and papers...but who knows. Anyway, if you're in need of software development help, please let me know! I enjoy imaging and vision work. Thanks for stopping by!

A good tutorial for linux based machines can be found here: A BEGINNER'S TUTORIAL by JERÂ?OME LANDRE.

A good tutorial on using OpenCV can be found below, a little windows build specific but good for starters.
A OpenCV tutorial by Robert Laganière

Lagniere's research group is also doing some very nice projects.

A little background on the Hough Transform

Look on google/yahoo for ICCV(international conference on computer vision) and ECCV (European conference on computer vision) and you'll find some very good papers on computer vision.
The very first publication about OpenCV was: Intel's Computer Vision Library: Applications in Calibration, Stereo, Segmentation, Tracking, Gesture, Face and Object Recognition.
The latest one is Latest

A wonderful paper on:

Building OpenCV from CVS

I'm a firm believer in code management through code revisioning... so I like to develop on the trunk.

To checkout the opencv library, check out the code using the pserver (why haven't we switched to SVN?!): :pserver: This e-mail address is being protected from spambots. You need JavaScript enabled to view it :/cvsroot/opencvlibrary open

Mac OS X OpenCV Port If you use the above information, you might want to add the following to your environment so that you can use the pkg-config.
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Building directshow portion of OpenCV

Make sure to install the Windows SDK (not old platform SDK).
Build "C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\Multimedia\DirectShow\dshowsamples.sln" for debug and release.
Add "C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\Multimedia\DirectShow\BaseClasses" to your global include path.
Add "C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\Multimedia\DirectShow\BaseClasses\Debug" and "C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\Multimedia\DirectShow\BaseClasses\Release" to your global library path.
If you get an error: "syntax error : identifier 'CAMSchedule'" is has to do with search order and precedence. Move your include path for the sample above the normal SDK include path.
Re: Base classes compile problem with Vista SDK - MSDN Forums
Then, you might also get some errors on the gl\glaux.h include, this file was removed from the Windows SDK...it used to be in the platform SDK. Comment it out, it should compile file.
