JPEG Based Conditional Entropy Coding for Correlated Steganography
Correlated steganography considers the case in which the cover Work is chosen to be correlated with the covert message that is to be hidden. The advantage of this is that, at leas...

Energy-neutral source-channel coding in energy-harvesting wireless sensors
Abstract—This work addresses the problem of energy allocation over source compression and transmission for a single energy-harvesting sensor. An optimal class of policies is iden...
