| 摘 要： | 盲数字水印是数字作品版权保护系统的关键技术之一。由于在检测时没有原始图像作为参考 ,所以水印检测器的设计成为盲水印算法的核心。基于图像小波变换系数的局部平稳高斯模型 ,提出了一种新的盲水印检测器。实验结果表明该检测器与被广泛应用的线性相关检测器相比具有更好的鲁棒性

| Abstract: | Blind image digital watermarking, which can detect watermark without using the original image, is a key technique for the practical intellectual property protecting system For its good performance in image analysis and image compression, wavelet based digital watermark algorithm has become the mainstream in the digital watermark research Based on the local Gaussian model of wavelet coefficients, we propose a new blind watermark detector A series of experimental results show that it is more robust than linear correlation detector |

| Keywords: | digital watermarking blind watermark detector local gaussian model |
