Display sequence of images using matplotlib

Question

I have this simple python script using OpenCV to load images from a folder and display them in a loop. I want to reproduce this effect using matplotlib.

I have implemented a handy script based on matplotlib that just suits your need and much more. Check it here

In your case, the following snippet should work:

import os
from scipy.misc import imread

img_files = [for f in os.listdir('.') if f[-3:] == 'png']

# redraw_fn draw frame f in a image sequence
def redraw_fn(f, axes):
    img_file = img_files[f]
    img = imread(img_file)
    if not redraw_fn.initialized:
        redraw_fn.im = axes.imshow(img, animated=True)
        redraw_fn.initialized = True
    else:
        redraw_fn.im.set_array(img)
redraw_fn.initialized = False

videofig(len(img_files), redraw_fn, play_fps=30)
