I'm working on some computer vision algorithm and I'd like to show how a
numpy array changes in each step.What works now is that if I have a simple
imshow( array ) at the end of my code, the window displays and shows the
final image.However what I'd like to do is to update and display the imshow
window as the image changes in each iteration.So for example I'd like to
do:The problem is that this way, the Matplotlib window doesn't get
activated, only once the whole computation is finished.I've tried both
native matplotlib and pyplot, but the results are the same. For plotting
commands I found an .ion() switch, but here it doesn't seem to work.Q1. What
is the best way to continuously display updates to a numpy array (actually a
uint8 greyscale image)?Q2. Is it possible to do this with an animation
function, like in the dynamic image example? I'd like to call a function
inside a loop, thus I don't know how to achieve this with an animation
function.
