is_page_empty
A simple package/script that checks whether a given image file is empty.
Install it with one of the optional dependencies skimage, imageio, or pil or provide that skimage, imageio, or pillow are installed.
Then you can check whether an image file is empty using the commandline:
if is_page_empty some_image.png; then echo "Yes, it's empty"; else echo "No, it's not empty."; fi
Or you can use the package to check programmatically
import is_page_empty
if is_empty('path/to/image/file.png'):
print("That file is empty.")
The script simply cuts the page into small squares, counts the number of pixels below a certain threshold in each, and compares the sum of those numbers in the squares with the highest numbers to a cutoff threshold.
This has been very robust, in my experience, for scanned text; in particular in double-sided prints, where some of the print on the other side may shine through, and in pages with punched holes, which are rendered black in the print.
