摘要：This paper, a robust image watermarking scheme for copyright protection based on Dual Tree Complex Wavelet Transform (DT-CWT) and Visual Cryptography concept (VC) is presented. The proposed scheme embeds the watermark without modifying the original host image. In the embedding process, the original image is transformed in the complex wavelet domain then, according to LL sub-band features and VC, a secret share is generated. This later is required to extract the watermark from the attacked image in the extraction process. To improve the clarity of the extracted watermark, a post process called reduction procedure is also proposed. The experimental results show that the proposed method can withstand several image processing attacks such as cropping, filtering and compression etc.
