摘要
论述了一种基于DCT变换域的数字图像水印技术的实现方法.该技术可以使嵌入的数字图像水印具有不可见性,并且原图像信息丢失量少,还能够抵抗如剪切、缩放和抗噪声等一系列攻击,具有很好的鲁棒性.
A DCT domain digital image watermarking technology is discussed. It makes the watermarking perceptually invisible, and there is a little loss of relevant of the original image. By using the prosperity of DCT, watermarking image is robust against attack, such as cutting, rotating and noise interfering etc.
