Cramer–Rao lower bounds for change points in additive and multiplicative noise [PDF]
, 2004 The paper addresses the problem of determining the Cramer–Rao lower bounds (CRLBs) for noise and change-point parameters, for steplike signals corrupted by multiplicative and/or additive white noise. Closed-form expressions for the signal and noise CRLBs

Detection and Estimation of Abrupt Changes contaminated by Multiplicative Gaussian Noise [PDF]
, 1998 The problem of abrupt change detection has received much attention in the literature. The Neyman Pearson detector can be derived and yields the well-known CUSUM algorithm, when the abrupt change is contaminated by an additive noise.

A Fractional-Order Telegraph Diffusion Model for Restoring Texture Images with Multiplicative Noise
Fractal and Fractional, 2023 Multiplicative noise removal from texture images poses a significant challenge. Different from the diffusion equation-based filter, we consider the telegraph diffusion equation-based model, which can effectively preserve fine structures and edges for ...

A Convex Variational Approach for Image Deblurring With Multiplicative Structured Noise
IEEE Access, 2020 The restoration of images corrupted by blurring and structured noise has attracted growing attention in the domains of image processing and computer vision. However, many works only focus on the restoration of the images degraded by blurring and additive
