Multiplicative Noise Removal Using L1 Fidelity on Frame Coefficients
Sylvain Durand, Jalal Fadili, Mila Nikolova
We address the denoising of images contaminated with multiplicative noise, e.g. speckle noise. Classical ways to solve such problems are filtering, statistical (Bayesian) methods,…

Approximate Controllability for Linear Stochastic Differential Equations in Infinite Dimensions
D. Goreac
The objective of the paper is to investigate the approximate controllability property of a linear stochastic control system with values in a separable real Hilbert space. In a firs…
