Another interesting library that I would like to learn more about is Gandalf.  Gandalf is another vision library written in C.  It provides many of the things that OpenCV provides.  Like feature detection, camera modeling (fundamental matrix solving), hough transforms, etc.  However, it seems there is little out there in way of research papers that use the library.  I'm also having trouble just finding projects using it on the web.

Vision is something that has been missing from computers since the beginning.  Today we are finally getting the harddrive space, the cameras, and the horse power to actually handle the job.  I just bought an iMac with an integrated 640x480 camera with integrated microphone.  You can pickup a pan/tilt (1.3 Megapixel, again with noise cancelling microphone) camera for under 120 bucks.... amazing.

The next thing that is really exciting... is that manufacters like logitech are finally creating their own vision SDKs.  This means that you can write software for a manufacterer.... hardware accelerated...and supported across multiple platforms and OSes.  Very powerful.

So I have yet to use the logitech vision SDK... but here are some links on the new tech.  I'll let you know what I find. Check back on this page soon.
