I want to set up a rapid loop of updating a screen with some image data and then fetching the result with a webcam that is pointed at the screen (the idea is to sample hundreds of cycles, change some external filter between the screen and camera, and sample again).
How can I update an already existing imshow
Dict
with new image data? The new data has the same dimensions and type as the old one. The updated imshow
window should not move in relation to the physical screen from update to update.
I’m convinced that I need to connect the call to imshow
with a Signal
of an image, and then just push!
to that signal, but I can’t get it to work…
Thanks!!!
