Estimating the Information Theoretic Optimal Stego Noise
We recently developed a new benchmark for steganography, underpinned by the square root law of capacity, called Steganographic Fisher Information (SFI). It is related to the multip...

Situated Software Development: Work Practice and Infrastructure Are Mutually Constitutive
Software developers’ work is much more interesting and multifarious in practice than formal definitions of software development processes imply. Rational models of work are ofte...

Deformable trellis: open contour tracking in bio-image sequences
This paper presents an open contour tracking method that employs an arc-emission Hidden Markov Model (HMM). The algorithm encodes the shape information of the structure in a spati...

Cramer-Rao lower bound on doppler frequency of coherent pulse trains
This paper derives the Cramer-Rao lower bound (CRLB) on estimates of the frequency of a coherent pulse-train passively intercepted at a moving antenna. Such estimates are used to ...

An Information Model for Geographic Greedy Forwarding in Wireless Ad-Hoc Sensor Networks
—In wireless ad-hoc sensor networks, an important issue often faced in geographic greedy forwarding routing is the “local minimum phenomenon” which is caused by deployment ho...
