DCT变换域中的自适应图像水印算法
Adaptive image watermarking algorithm in DCT domain
摘要
Abstract
The article proposes a digital watermarking algorithm based on DCT transform. The method can adaptively select the watermark embedding position. According to human visual properties, it also reasonably allocates the watermark embedding strength in the different position. In addition, the combination of chaotic sequence and scrambling technology enhances the attackde ability. Verified by the experiment, the method basically meets the demand of invisibility and robustness, and especially has stronger ability to resist JPEG compression attack.关键词
