Opencv imshow() freezes when updating

Question

For my image processing algorithm I\'m using python / OpenCV. The output of my algorithm shall be updated im the same window over and over again.

However sometimes

Answer 1

My suggestion is to use Matplotlib pyplot for displaying the image. I do it the following way.

import matplotlib.pyplot as plt
# load image using cv2....and do processing.
plt.imshow(cv2.cvtColor(image, cv2.BGR2RGB))
# as opencv loads in BGR format by default, we want to show it in RGB.
plt.show()

I know it does not solve the problem of cv2.imshow, but it solves our problem.
