A method for automatic identification of signatures of steganography software
Abstract--A fully automated, blind, media-type agnostic approach to steganalysis is presented here. Steganography may sometimes be exposed by detecting automatically characterized ...

Rate-distortion optimized on-demand media streaming with server diversity
This paper studies the streaming of packetized media from multiple servers to a client over a lossy network. In particular, we propose a client-driven rate-distortion optimal pack...

On the Complexity of Rate-Distortion Optimal Streaming of Packetized Media
We consider the problem of rate-distortion optimal streaming of packetized media with sender-driven transmission over a single-QoS network using feedback and retransmissions. For ...

Interactive Rendering of Non-Constant, Refractive Media Using the Ray Equations of Gradient-Index Optics
Existing algorithms can efficiently render refractive objects of constant refractive index. For a medium with a continuously varying index of refraction, most algorithms use the r...
