Filter Evaluation for DWT-Domain Image Watermarking

چکیده

Similar to other wavelet-based image processing algorithms, the choice of wavelet filters generally affects the performance of a wavelet-based watermarking system. In this Letter, we evaluate a set of biorthogonal integer wavelets under a multiresolution-watermarking framework. Further investigation is conducted to justify the robustness performance against attacks.

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 ...

Intelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms

Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
