WAVELET-BASED DIGITAL WATERMARKING ALGORITHM

摘要：

The paper proposes a Wavelet-based watermarking algorithm where watermark information is embedded in the multilevel wavelet coefficients of the cover image. Data embedding in sub-bands through applying the proposed algorithm which provides a good performance between the transparency and the robustness of watermarks increases the security of watermark information hiding. Experimental results show watermark embedded by the proposed algorithm is effective and robust against common noise and image processing operation.
