Digital Image-in-Image Watermarking of Remote Sensing Images

چکیده
In this paper, we present a watermarking technique for hiding an entire image or pattern as a watermark into remotesensing images. In our technique, the Karhunen Loève Transform (KLT) is preliminarily applied on the multispectral image. The most principal component image is used for embedding with a watermark. The embedding process is performed in a middlefrequency subband resulted by a two-dimension wavelet transform. Finally, the multispectral image containing the watermark is obtained by the inverse KLT. Experimental results on LANDSAT images showed that the proposed watermarking technique is robust to various kinds of 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 ...
