What is this?
This is a Python library for blind, invisible image watermarking: you embed a hidden watermark into an image and can later extract it without needing the original, un-watermarked image.
This is a Python library for blind, invisible image watermarking: you embed a hidden watermark into an image and can later extract it without needing the original, un-watermarked image.Is this a library or a command-line tool?It is a Python library that can also be driven straight from the command line, so you can either import it in Python code or run bash commands to embed and extract watermarks.

You can embed a text string, another image, or a raw array of bits as the watermark payload.Why doesn't extraction need the original image?The library is a 'blind' watermarking method by design, meaning the watermark can be pulled directly out of the watermarked image without comparing it to the original.
