Read video

In addition to pip install imageio, pip install imageio-ffmpeg is required to read video through imageio.

Because the images in the video are all color, you need to convert the rgb tricolor to a single intensity and put the converted image into a list.

Import imageioimport numpy as npimport matplotlib.pyplot as pltvideo = imageio.get_reader ('test.mp4') imgs = [] for img in video: imgs.append (np.mean (img,2)) plt.imshow (imgs [0]) plt.show ()

Convert to character

Although this video has been compressed, it is still too large for the character painting, so it needs to be further compressed before converting the character painting. The simplest method is taken here-that is, to average the adjacent pixels.

# reduce the width of the image to widthfrom itertools import product # for circular nesting def resizeImg (img,w,h=None): Mrecine n = img.shape if n
