library for image processing, computer vision and machine learning

How can someone use Qt for image processing , computer vision and machine learning? Are there libraries or plugins for Qt for this purpose?
which one is best?

thanks

I suggest you have a look at the very popular OpenCV library: http://opencv.org/
As it's a C++ library you can use it easily in a C++ Qt project.

thanks @Joel-Bodenmann
I found OpenCV, QVision, QCV, VXL and etc,
do you know which one is better?

Sorry, I can't really comment on that as I haven't used anything other than OpenCV so far. All I can tell you is that OpenCV is very popular and known to work well. It's also actively maintained and used throughout the industry.
QCV appears to be a Qt friendly wrapper around the OpenCV library. I've never used it. Neither have I ever touched VXL and QVision appears to be something completely different.

I'm sorry that I can't give any objective recommendation. Probably somebody else has more experience on this field.
