Watermarking of Raw Digital Images in Camera Firmware
In this article we investigate 'real-time' watermarking of single-sensor digital camera images (often called 'raw' images) and blind watermark detection in demosaicked images. We describe the software-only implementation of simple additive spread-spectrum embedding in the firmware of a digital camera. For blind watermark detection, we develop a scheme which adaptively combines the polyphase com...

A Note to All Readers This is not an original electronic copy of the master's thesis, but a reproduced version of the authentic hardcopy of the thesis. I lost the original electronic copy during transit from India to USA in December 1999. I could get hold of some of the older version of the files and figures. Some of the missing figures have been scanned from the photocopy version of the hardco...
متن کاملDigital Watermarking of Raw and Compressed Video
Embedding information into multimedia data is a topic that has gained increasing attention recently. For video broadcast applications, watermarking of video, and especially of already encoded video, is interesting. We present a scheme for robust interoperable watermarking of MPEG-2 encoded video. The watermark is embedded either into the uncoded video or into the MPEG-2 bitstream, and can be re...
متن کاملDigital Watermarking Of Satellite Images
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 ...
