This work was a part of course project of 'Digital Image Processing' course during my MSc. class.
Digital watermarking is a technique to hide the copyright information into the digital data through certain algorithm.
The watermark:
- is embedded into the host media to be protected, such as an image, audio or video.
- can be detected or extracted later to make an assertion about the host media.
- should not alter the quality and visually of the host image and it should be perceptually invisible.
- robust with respect to image distortions, i.e.
- difficult for an attacker to remove
- robust to common image processing and geometric operations, such as filtering, resizing, cropping and image compression.
Try to run the notebook file to figure it out by your own.
