opencv vs emgu vs qt

edit

Hello all

I would like to ask for a little advice. I see opencv is very powerfull but to create a program that many will use a gui is really required because many cannot understand command line. Why does opencv not include a gui interface by default?

Now if I want to create a gui app I have the option of emgu, qt and opencvsharp as I can see. opencvsharp seems to have the least amount of documentation, so I guess that aint really my 1st choice.

I really liked QT but the debug folder for just a simple open file dialog app to show an image and convert it to canny came to be over 600mb.

So I had a look at emgucv and I am the most familiar with csharp but now I have read so many tutorials on opencv and it seems the syntaxes are different everywhere.

The main purpose is going to be OCR text detection using a live video feed.

What application do you guys recommend I use?

Thanks
