Gabor transform domain watermarking

چکیده
Transform domain is the most commonly used space for watermarking applications. Most of the common frequency transforms have been used for this purpose. In this work we investigate the use of the Gabor transform in traditional watermarking schemes. A casting method and detection results are thoroughly examined. It seems that traditional detection thresholds are not applicable in this transform, thus a modified approach is employed to overcome this problem. Experimental results are quite encouraging.

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 ...
