Witryna28 sty 2024 · 6. Starting with two images im1 and im2 created with the PIL module, we have the corresponding black and white images, bw_im1 = im1.convert ('1') and. bw_im2 = im2.convert ('1') Each pixel of bw_im2 and bw_im2 is either 0 or 256. Suppose both bw_im2 and bw_im2 have the same size. How do you XOR all the corresponding … Witryna23 lut 2024 · If I compare both images using an online image comparison tool I can see traces of a new image containing what seems to be the solution to the puzzle. However, I don't think this is the intended way to solve this puzzle. So I tried to write a program to XOR the two encrypted images together, because the XORed keys should cancel out …
