Digital Watermarking Of Satellite Images
نویسندگان
چکیده
A novel watermarking algorithm is proposed for copyrighting of satellite images based on a table look-up method in pixel domain which does not distort certain specific regions in the original image. A visually meaningful watermark is embedded invisibly and irreversibly in the host image, preserving the vital areas. This watermark is embedded in such a way that it can be easily extracted on the production of the watermarking key, constituted by the look-up table.

Digital watermarking has been proposed to increase the digital data security, confidentiality and integrity. Satellite image watermarking is a special category of image watermarking in the sense that the images have special requirements. Particularly, watermarked satellite images should not differ perceptually from the original counterparts, because the purpose of taking the image must not be v...

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...
