Image Denoising in Mixed Poisson–Gaussian Noise [PDF]
IEEE Transactions on Image Processing, 2011 We propose a general methodology (PURE-LET) to design and optimize a wide class of transform-domain thresholding algorithms for denoising images corrupted by mixed Poisson-Gaussian noise. We express the denoising process as a linear expansion of thresholds (LET) that we optimize by relying on a purely data-adaptive unbiased estimate of the mean-squared

EXPONENTIAL MIXING FOR SOME SPDEs WITH LÉVY NOISE [PDF]
Stochastics and Dynamics, 2011 We show how gradient estimates for transition semigroups can be used to establish exponential mixing for a class of Markov processes in infinite dimensions. We concentrate on semilinear systems driven by cylindrical α-stable noises introduced in [18], α ∈ (0,2).

PINK NOISE SEBAGAI GUIDE DALAM MIXING
Sorai: Jurnal Pengkajian dan Penciptaan Musik, 2023 Pink noise adalah noise yang memiliki intensitas bunyi sama kuatnya pada tiap oktaf. Populernya pink noise sebagai bunyi yang ramah di telinga manusia juga telah didukung oleh beberapa riset psikologi dan neuroscience. Kecenderungan intensitas bunyi dan frekuensi dalam pink noise searah dengan teori Fletcher Munson yang merupakan kecenderungan dari ...

Smart Switching Bilateral Filter with Estimated Noise Characterization for Mixed Noise Removal [PDF]
Mathematical Problems in Engineering, 2019 Traditionally, several existing filters are proposed for removing a specific type of noise. However, in practice, the image communicated through the communication channel may be contaminated with more than one type of noise. Switching bilateral filter (SBF) is proposed for removing mixed noise by detecting a contaminated noise at the concerned pixel ...

Getting information from the mixed electrical-heat noise
, 2017 We give a classification of the different types of noise in a quantum dot, for variable temperature, voltage and frequency. It allows us first to show which kind of information can be extracted from the electrical noise, such as the ac-conductance or the

Noise-enhanced trapping in chaotic scattering [PDF]
, 2010 We show that noise enhances the trapping of trajectories in scattering systems. In fully chaotic systems, the decay rate can decrease with increasing noise due to a generic mismatch between the noiseless escape rate and the value predicted by the ...

Minimal excitation states for heat transport in driven quantum Hall systems
, 2017 We investigate minimal excitation states for heat transport into a fractional quantum Hall system driven out of equilibrium by means of time-periodic voltage pulses.

Hardy's proof of nonlocality in the presence of noise
, 2006 We extend the validity of Hardy's nonlocality without inequalities proof to cover the case of special one-parameter classes of non-pure statistical operators.

Mixing Oscillators for Phase Noise Reduction [PDF]
IEEE Signal Processing Letters, 2016 The output of oscillators is usually not stable over time. In particular, phase variations---or \emph{phase noise}---corrupts the oscillations. In this letter, we describe a circuit that designed to average the phase noise processes and frequency offsets in frequency-matched oscillators.
