本文提出了一种新的盲水印方案，该方案在小波域中嵌入数字图像签名/水印，并利用独立分量分析（ICA）技术进行盲水印提取。水印被插入到中频子带中。利用视觉掩蔽函数对数字签名进行修改，以保证水印图像的感知质量。采用独立分量分析（ICA）方法在不需要原始图像的情况下进行盲水印提取。该方法已成功地与其他基于小波的盲水印技术进行了评估和比较，以对抗最突出的攻击，如JPEG和JPEG2000压缩和量化。
In this paper, we propose a new blind watermarking scheme by embedding a digital image signature/watermark in the wavelet domain and using Independent Component Analysis (ICA) technique for blind watermark extraction. The watermark is inserted in the middle frequency sub-bands. A visual masking function is used to modify the digital signature to assure the perceptual quality of the watermarked image. Independent Component Analysis (ICA) method is employed for blind watermark extraction without requiring the original image. The presented technique has been successfully evaluated and compared with other wavelet-based blind watermarking techniques against the most prominent attacks, such as JPEG and JPEG2000 compression and quantization.
