Surmounting the Effects of Lossy Compression on Steganography
- In National Information System Security Conference
, 1996
"... Steganographic techniques can be used to hide data within digital images with little or no visible change in the perceived appearance of the image and can be exploited to export sensitive information. Since images are frequently compressed for storage or transmission, effective steganography must em ..."

employ coding techniques to counter the errors caused by lossy compression algorithms. The Joint Photographic Expert Group (JPEG) compression algorithm, while producing only a small amount of visual distortion, introduces a relatively large number of errors in the bitmap data. It is shown that, despite
Lossy Compression of Dynamic, Weighted Graphs
"... Abstract—A graph is used to represent data in which the relationships between the objects in the data are at least as important as the objects themselves. Large graph datasets are becoming more common as networks such as the Internet grow, and our ability to measure these graphs improves. This neces ..."

. This necessitates methods to compress these datasets. In this paper we present a method aimed at lossy compression of large, dynamic, weighted graphs. Keywords-graph compression; dynamic, weighted graphs; shrinkage; I.
Improvements On Data Hiding For Lossy Compression
, 2002
"... Compression is the most common application that all forms of multimedia data undergo. Lossy nature of the compression due to the use of quantizers should be taken into account by the watermarking technique employed. In this paper, we present a data hiding scheme that incorporates the embedding with ..."

Interactive Lossy Compression for Images and Video
"... Abstract—In any given scene, a human observer is typically more interested in some objects than others, and will pay more at-tention to those objects they are interested in. This paper aims to capture this attention focusing behavior by selectively merging a fine-scale oversegmentation of a frame so ..."

rules for images and videos based on defining a weighted distance metric between adjacent oversegments. We present as an example application of this technique a new lossy image and video stream compression method which attempts to minimize the loss in areas of interest. I.
