digital-watermarking

Implementation of algorithms DCT, DWT watermarking.

Reference repository https://github.com/Messi-Q/python-watermark/tree/master/image_digital_watermark/case3.

Source code was edited to be able to embed and extract the signature as an image.

Install all dependencies:

pip install -r requirements.txt

1. Embedding watermark into a cover:

python main.py --origin path_cover_image --ouput path_output_image

Example:

python main.py --origin cover.jpg --ouput watermarked.jpg

1. Then choice a type from “DCT” or “DWT”.
2. After that, choice “embedding”.

2. Extracting watermark from a watermarked image:

python main.py --origin path_watermarked_image --ouput path_extracted_signature

Example:

python main.py --origin watermarked.jpg --ouput signature.jpg

1. Then choice a type from “DCT” or “DWT”.
2. After that, choice “extracting”.

3. Attacking a watermarked image:

python main.py --origin path_watermarked_image --ouput path_attacked_image

Example:

python main.py --origin watermarked.jpg --ouput watermarked.jpg

1. Then choice “Attack”.
2. After that, choice a type attack.
