A Watermarking Scheme Based on the Parametric Slant-Hadamard Transform
نویسندگان
چکیده
In this paper, a watermarking scheme based on the parametric slant-Hadamard transform is presented. Our approach divides the image into separate blocks and applies the parametric slant-Hadamard transform on each block individually. Then based on a blind scheme, the watermark is inserted in the transform domain and the inverse transform is carried out. The advantage of the selected transform is contribution of parameters that can be used to change the requirements of watermarking such as fidelity and robustness. The changes of transform parameters can enhance the requirements of watermarking according to the applications. Experimental results show that the proposed technique has different fidelity and robustness based on different parameters in watermarking scheme.

Slant transform watermarking for digital images
In this paper, we propose a digital watermarking algorithm based on the Slant transform for the copyright protection of images. Our earlier research work associated with the fast Hadamard transform for robust watermark embedding and retrieval of images and characters suggests that this transform could also provide a good “hidden” space for digital watermarking. The Slant transform has many simi...
متن کاملA Slant Transform Watermarking for Copyright Protection of Satellite Images
In this paper, we propose a digital watermarking algorithm based on the Slant transform for the copyright protection of satellite images. Designed to match basis vectors to areas of constant luminance slope, the Slant transform is good for compact energy in “smooth” images. However, our earlier research work suggests that in terms of watermarking, it works better for textured images, for the en...
متن کاملTexture Feature Extraction using Slant-Hadamard Transform
Random and natural textures classification is still one of the biggest challenges in the field of image processing and pattern recognition. In this paper, texture feature extraction using Slant Hadamard Transform was studied and compared to other signal processing-based texture classification schemes. A parametric SHT was also introduced and employed for natural textures feature extraction. We ...
متن کاملA 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 ...
