Opencv provides are useful, but limited, method of building a GUI. A much more complete system could be acheived using pyqt.The question is, how do we display images. There are quite a few possible routes but perhaps the easiest is to use QLabel since it has a setPixmap function. Below is some code that creates two labels. It then creates a grey pixmap and displays it one of the labels. code: staticLabel1.py

It should look like this:

Ok, so how do with display an image. Well we could us Qt to load the image directly, but I want to do this with opencv so it can be integrated into a computer vision app. To do this load the image with cv2.imread and then we convert this to a QPixmap and rescale. Here is an example

So can we now use this to display video? We could open the webcam and update our image every frame. liveLabel1.py attempts to do this - but it does not work. The problem is the video capture loop is blocking the processing. This means the message system that Qt uses to do things like draw the widgets never gets called. We need to fix this by capturing the webcam in a seperate thread. Here's the code:

Note, we send a numpy array using PyQt's signal slot mechanism to ensure thread saftey. This should now display live images for your webcam. There might, however, be a error created when you close the app. This is because the capture device has not been shutdown correctly. (On my mac this does not happen, but on my Linux machine it does). To sovle this we need to override App's closeEvent function and single to the thread to shut down.
