Description: 基于DCT的数字水印处理技术，本水印处理过程利用图像的缩放技术和调整原始图像的直方图，根据人眼视觉特性,在每个DCT变换块的DC分量上嵌入水印信息，并且在水印信息嵌入之前,对其进行置乱加密,提供双重安全保证，接着通过JPEG压缩攻击对DCT域的鲁棒性进行测试，证明了DCT的抗攻击能力。-DCT-based digital watermarking technique, the watermark processing technology and the use of image scaling to adjust the original image histogram, according to the human visual system, in each block of DCT-DC components on the embedded watermark information, and information in the watermark embedding prior to its scrambling encryption to provide double security guarantees, followed by JPEG compression attacks on the DCT domain robustness of tests to demonstrate the anti-attack capability of DCT.
