摘　　要：数字水印技术是近年来图像数据保护的一个重要研究领域,论文通过对水印技术的空域与交换域的分析,提出一种用于数字图像版权识别的空域与DCT域相结合的数字水印算法。算法使用MATLAB仿真软件实现,实验结果证明,该算法简单易行,具有很好的视觉效果,而且对JPEG压缩、中值滤波以及噪声干扰等都具有较强的鲁棒性。Digital watermarking technology is an important research in image data protection areas recent years. Through the airspace of watermarking technology and the exchange of domain analysis, put forward a kind of airspace for digital image copyright recognition combined with DCT domain digital watermarking algorithm is proposed. Algorithm using MATLAB simulation software implementation. The experimental results show that this algorithm is simple, has the very good visual effect, but also to JPEG losses compression, median filtering and noise and so on all has strong robustness.
