Wavelet based digital art protection
Abstract
This thesis objective is to provide a robust watermarking algorithm to protect digital images.
The proposed algorithm is using wavelet-based watermarking in which we are investigating
how embedding in high-frequency subbands and low-frequency subbands would affect the robustness
of the watermark while facing typical signal processing attacks.
