OpenCV tutorial 2 - OpenCV 2.x objects and functions

Here is the second OpenCV tutorial video! In this video, we recreate the same program as in the first video, but with OpenCV 2.x objects and functions. Enjoy!

Worked like a charm.  I was a bit thrown off by the BGR switcheroo at first, but other than that, this was relatively simple.

Thanks for your tutorial. I was run your code correctly. But it cannot capture any circle in original window. Can you explain how can I fix it to capture the circles?

hi, I did everything like you said in this vid and it built fine in VS. But when debugging I keep running into a problem("vector iterator is incompatible.").
Can you help me with it? Thnx in advance.

Hello, when you use your code, it can be complied sucessfully, but the stack alwarys overflow when I run it. After debugging, I found that the overflow is caused by inRange and HoughCircles. I am sure everything else is ok becuase the code runs well when I common these two functions. Do u konw why? Thank you for your help!

Hi Thanks for the tutorial.you are a genius.
I have a question. why if i try to change the webcam with a recorded video it will run slow, and stop.

I change
p_capWebcam = cvCaptureFromCAM(0);
