An image watermarking technique based on pyramid transforms is proposed. An arbitrary binary pattern is formed into an effective hypothesized pattern and transmitted as a watermark. Multiresolution pyramid transforms are applied to host images, whose characteristics are exploited to embed the watermark. The detector is designed to be effective to a wide range of original signal sources and noise sources. The scheme is designed to achieve efficient trade-offs between perceptual invisibility, robustness and trustworthy detection. The experiments demonstrate that the proposed technique has high imperceptibility, good robustness, and accurate detection. It can be applied to copyright notification, enforcement, and fingerprinting.
