Hey, since sorting the image loses some data it's actually better to just perform the operations on the original image like so:
from PIL import Image
img = Image.open('second.png')
data = list(img.getdata())
width, height = img.size
out_image = ''
hist = {}
for p in data:
hist[p] = hist.get(p, 0) + 1
for p in data:
if hist[p] < 10:
out_image += '\xff'
else:
out_image += '\x00'
with open('out.data', 'wb') as f:
f.write(out_image)
And if you view the result as a bitmap, you get:
