Digital Watermarking Algorithm based on Wavelet Transform |
| |
| Abstract: | An embedding and detecting algorithm for digit al watermarking based on wavelet analysis is proposed,and the original image is no t required for detecting the watermark.The watermarking is embedded into the par ts of medium frequency coefficients to guarantee its invisibility and robustness .The experimental results show that the method is feasible and the embedded wate rmarks with the proposed algorithm are invisible and robust enough against the c ommonly used image processing. |
