Reversible Watermarking Scheme

This repository contains the implementation of a reversible watermarking scheme for image content authentication based on wavelet transform. The implementation is based on the paper "A reversible watermarking for image content authentication based on wavelet transform" by De Li, Xianlong Dai, Jiang Gui, Jinyan Liu, and Xun Jin.

Repository Structure

The repository contains the following files:

• Images:

  • baboon-color.jpg: Sample color image of a baboon used in the experiments.
  • baboon.jpg: Sample grayscale image of a baboon used in the experiments.
  • leena-color.png: Sample color image of Lena used in the experiments.
  • Lena-gray.png: Sample grayscale image of Lena used in the experiments.

• Jupyter Notebooks:

  • watermark-embedding-extraction-color-baboon.ipynb: Notebook for watermark embedding and extraction in color baboon image.
