摘要：

In this paper, a novel DCT based image watermarking scheme is proposed. The watermark bits are encoded by BCH code, and then embedded into the host by modulating the relationships between the selected DCT coefficients. Since the modulation is Jpeg compression like method, this approach improves the robustness against JPEG compression. Experimental results show good robustness against several image manipulations including Jpeg compression, noisy, low-pass filtering, shearing and so on. (c) 2012 Elsevier GmbH. All rights reserved.
