DCT-digital-watermarking-technology
提出了一种基于纠错编码的DCT域数字水印算法,该算法在检测时不需要原始图像,实现了盲检。并且对水印图像进行了利用超混沌置乱处理,提高了安全性能和抗攻击能力。纠错编码的引入使水印抗攻击能力明显增强。
(DCT digital watermarking algorithm based on error correction coding, the algorithm detected without the original image, blind. And watermark image of the the hyperchaotic scrambling process, improve the safety performance and anti-attack capability. The introduction of error correction coding watermark anti-attack capability significantly enhanced.)
