Obfuscating IEEE 802.15.4 communication using secret spreading codes
—The IEEE 802.15.4 standard specifies an M-ary spread spectrum system with public and fixed spreading sequences. We propose instead to use secret and dynamic, random spreading ...

A Hybrid Graphical Model for Robust Feature Extraction from Video
We consider a visual scene analysis scenario where objects (e.g. people, cars) pass through the viewing field of a static camera and need to be detected and segmented from the bac...
