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...

We consider the problem of actively learning the mean values of distributions associated with a finite number of options. The decision maker can select which option to generate t...

We investigate power estimation on a random noise from measurements taken by one-bit quantizers, with an efficacy assessed by the Fisher information. In isolated quantizers, an op...

Abstract—This paper proposes a new scheme based on information theoretical criteria to estimate the Channel-ImpulseResponse (CIR) length, whose accurate estimate represents one o...

In motion-compensated wavelet based video coders (MCWT), it is known that a precise motion estimation is necessary to minimize the wavelet coefficients energy. However, a motion v...
