Picklable image in python

Question

Does anyone know of a method to make images picklable? I am trying to pass OpenCV images between processes to separate display from real-time processing of an OpenCV video. I have tried PIL Image.tostring(), but to no avail. Is there a standard technique?

This is what you are looking for: pickleable image object

Making it a dict and then using the information in the dict to recreate the image again. Hopefully this helps

OpenCV's newer cv2 module uses NumPy arrays, which are inherently pickleable. See my answer here: https://stackoverflow.com/a/17054961/1510289
