Optimal Inversion of the Anscombe Transformation in Low-Count Poisson Image Denoising
—The removal of Poisson noise is often performed through the following three-step procedure. First, the noise variance is stabilized by applying the Anscombe root transformation ...

Suboptimal decentralized control over noisy communication channels
In this paper we present a technique for design of decentralized controllers for mean square stability of a large scale system with cascaded clusters of subsystems. Each subsystem...

Analysis of Nonlinear Transition Shift and Write Precompensation in Perpendicular Recording Systems
Abstract—In high density perpendicular magnetic recording channels, nonlinear transition shift (NLTS) is one of the distortions that can degrade the system performance. Write pre...

Generalized Window-Based PN Acquisition Scheme in CDMA Spread Spectrum Systems
In this letter, we propose a generalized version of the window-based pseudonoise (PN) acquisition scheme verifying one or more best hypotheses rather than the best one per search w...

Detection of Copy-Rotate-Move Forgery Using Zernike Moments
As forgeries have become popular, the importance of forgery detection is much increased. Copy-move forgery, one of the most commonly used methods, copies a part of the image and pa...
