Online course recommendation

I’m a big fan of online courses, especially the ones that feature good professors with valuable professional and teaching experience. It feels like you are at the university again, but from the comfort (or discomfort) of your chair at home.

The nodes can be applied on each other’s output in a pipeline-style way.

They can help to speed up your Computer Vision algorithms by masking the not interesting (defined by you) regions of the images.

The OpenCV, the Qt Creator and the Windows 7

(For the ones who did not get the title: Il buono, il brutto, il cattivo)

you might have just arrived at the right post in the Internet.

After you have downloaded the binaries for Windows, you get a nice README suggesting this:

If you have problems add build\bin and one of build\{x86|x64}\{vc9\vc10\mingw}\bin to your system path (to use DLLs)
