Watermarking Capacity of Digital Images Based on Domain-Specific Masking Effects
نویسندگان
چکیده
Our objective is to nd a theoretical watermarking capacity bound of digital images based on domain-speci c masking e ects. In this paper, we rst show the capacity of private watermarking in which the power constraints are not uniform. Then, we apply several domain-speci c Human Vision System approximation models to estimate the power constraints and then show the theoretical watermarking capacity of an image in a general noisy environment. Note that we consider all pixels, watermarks and noises are discrete values, which occur in realistic cases.

A Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

متن کاملEmbedding image watermarks in dc components
Both watermark structure and embedding strategy affect robustness of image watermarks. Where should watermarks be embedded in discrete cosing transform (DCT) domain in order for the invisible image watermarks to be robust? Though many papers in the literature agree that watermarks should be embedded in perceptually significant components, dc components are explicitly excluded from watermark emb...
