How to create multiple frames in a single frame to display input as welll as output?

问题

I am creating a programs that detects number of fingers and displays them. Further I'll be updating it to addition of multiple digit numbers. I saw this video on youtube and I wonder how he managed to split his input and output screen into 2 different screens? my current program displays the text in the frame itself

.

in the given picture he has divided his output screen into 2 screens one that displays the video cam and another displays its output. I need help to understand how he did it?

回答1:

i assume you are using pycv

if you use np.vstack or np.hstack you can see the stacked images.
