摘　　要：该文在基于DCT的二维实值离散Gabor(RDGT)变换的基础上提出了一种在静态图像中嵌入二维图像作为水印的图像水印实现技术。实验证明,该文所提议的算法具有较好的透明性,对如JPEG有损压缩,剪切,噪声等具有较好的稳健性。An efficient watermarking scheme for digital images is presented,in this paper,based on the 2D real-valued discrete Gabor transform(RDGT) by embeddingd 2D image as a meaningful watermark into a static image.Experimental results show good robustness of the approach against JPEG compression and other common image processing manipulations.
