摘要：
In this paper a robust watermarking scheme based on Dual Tree Complex Wavelet Transform (DT-CWT) is proposed. The embedded watermark image is preprocessed with a random location matrix. The original image is transformed in the complex wavelet domain by using DT-CWT then, according to the characteristics of the image data, the preprocessed watermark image is adaptively spread spectrum and added into the host image DT-CWT coefficients. The watermark detection process is accomplished without referring to the original image. Simulation results are presented to demonstrate the effectiveness of the proposed algorithm.
