Look at the rightmost bit of each byte.
In a grayscale image, each pixel is typically stored as an 8‑bit number (0–255). Instead of looking at the full number, a bit plane isolates just across all pixels. bit planes unblocked
for bit in range(8): plane = (pixels >> bit) & 1 # isolate one bit plane_img = Image.fromarray(plane * 255) # 0→black, 1→white plane_img.save(f'bitplane_bit.png') Look at the rightmost bit of each byte
A bit plane is a way of breaking down a digital image into its constituent binary bits. bit planes unblocked
from PIL import Image import numpy as np img = Image.open('your_image.jpg').convert('L') # grayscale pixels = np.array(img)
