Digital Watermarking Of Satellite Images.
Yogesh K. Chauhan, Palak Gupta, Kantilal L. Majumder · 2002
In this paper an efficient watermarking algorithm is proposed for copyrighting of satellite images. A look-up table method in pixel domain that does not distort certain specific regions in the original image has been used. A watermark is embedded invisibly and irreversibly in the host image without disturbing the vital areas of ones interest. This watermark is embedded in such a way that it can be easily extracted on the production of the watermarking key.
