Can someone please tell me how to use the guide push button to take a snapshot from the webcam and display the same in the gui ?

I am not able to write the code for taking the snapshot at the press of a push button.

The question is very general and in consequence hard to answer. Please post what you have tried so far and explain, which problems occur.

The main change would be that instead of

imshow(img)

"Note: If you are building a GUI where you want to control the figure and axes properties, be sure to use the imshow(..., 'Parent', ax) syntax."

See attached demo. It's still under development and may need some tweaks, but it works, at least for me. It also handles multiple cameras and if you have multiple cameras, it will ask you which one to use. It works for me and my integrated webcam and Lumenera USB camera. When I installed it on two macbooks, they had to make some changes, like to the desired default camera name.
