本文提出了一种基于量化的水印方法，该方法可以独立于原始图像的特征生成所需图像质量的水印图像。为了保证图像质量，该方法利用信号能量的变换域和空间域之间的关系。该方法从水印图像中提取嵌入水印序列，而不参考任何原始图像。
This paper proposes a quantization-based watermarking method that generates watermarked images of a desired image-quality independently of the characteristics of the original images. To guarantee the image-quality, this method utilizes the relationship between a transformed domain and the spatial domain for the signal energy. The proposed method extracts an embedded watermark sequence from a watermarked image without referring to any original images.
