An Adaptive Estimation Method for Heterogeneous Group Targets with Uncertain Multiplicative and Additive Noises [PDF]
SensorsIn this paper, an adaptive estimation algorithm for heterogeneous group targets considering uncertain multiplicative and additive noises is proposed. Firstly, a state-space model for heterogeneous group targets with composite multiplicative and additive ...

When multiplicative noise stymies control [PDF]
Annals of Applied Probability, 2019 We consider the stabilization of an unstable discrete-time linear system that is observed over a channel corrupted by continuous multiplicative noise. Our main result shows that if the system growth is large enough, then the system cannot be stabilized in a second-moment sense.

Anisotropic Diffusion Based Multiplicative Speckle Noise Removal
Sensors, 2019 Multiplicative speckle noise removal is a challenging task in image processing. Motivated by the performance of anisotropic diffusion in additive noise removal and the structure of the standard deviation of a compressed speckle noisy image, we address ...

An Additive Approximation to Multiplicative Noise [PDF]
Journal of Mathematical Imaging and Vision, 2020 Multiplicative noise models are often used instead of additive noise models in cases in which the noise variance depends on the state. Furthermore, when Poisson distributions with relatively small counts are approximated with normal distributions, multiplicative noise approximations are straightforward to implement. There are a number of limitations in

Media Statistika, 2021 The regression model that can be used to model spatial data is Spatial Autoregressive (SAR) model. The level of accuracy of the estimated parameters of the SAR model can be improved, especially to provide better results and can reduce the error rate by ...

SYNCHRONIZATION OF SYSTEMS WITH MULTIPLICATIVE NOISE [PDF]
Stochastics and Dynamics, 2008 The synchronization of Stratonovich stochastic differential equations (SDE) with a one-sided dissipative Lipschitz drift and linear multiplicative noise is investigated by transforming the SDE to random ordinary differential equations (RODE) and synchronizing their dynamics.

Fractal and Fractional, 2021 In this paper, we consider the stochastic fractional-space Chiral nonlinear Schrödinger equation (S-FS-CNSE) derived via multiplicative noise. We obtain the exact solutions of the S-FS-CNSE by using the Riccati equation method. The obtained solutions are

The use of ICA in multiplicative noise [PDF]
Neurocomputing, 2006 When a linear mixture of independent sources is contaminated by multiplicative noise, the problems of blind source separation and feature extraction are highly complex. Specifically, the approach followed by the independent component analysis does not produce proper results. This is because the output of a linear transformation of the noisy data cannot

A Weberized Total Variation Regularization-Based Image Multiplicative Noise Removal Algorithm
EURASIP Journal on Advances in Signal Processing, 2010 Multiplicative noise removal is of momentous significance in coherent imaging systems and various image processing applications. This paper proposes a new nonconvex variational model for multiplicative noise removal under the Weberized total variation ...
