grayscale image processing

[zyb1003]

We'll need to see what code you have so far.  As long as you can access the images as arrays it shouldn't be too hard.  Not sure if PIL uses numpy or not but if it does it will make things easier.

from PIL import Image
from pylab import *
im=array(Image.open('0.1v.jpg').convert('L'))
print(im)

So far, this is the code I have. Now I can read every pixel's grayscale value.
