Optimal strategies for spread-spectrum and quantized-projection image data hiding games with BER payoffs
We analyze spread-spectrum and quantization projection data hiding methods from a game-theoretic point of view, using the bit error rate (BER) as the payoff, and assuming that the...

Multiple Description Coding for Stationary and Ergodic Sources
We consider the problem of multiple description (MD) coding for stationary sources with the squared error distortion measure. The MD rate region is derived for the stationary and ...
