摘要：
This paper presents a new watermarking scheme using the pattern-based image normalization. The proposed method extracts an image-adaptive binary pattern (BP) composed of inner regions, and the geometric moments are computed using the BP rather than the source image itself. This approach avoids any misalignment between the normalized images on both sides of embedding and detection, which is inevitable when the source image itself is used.
