extremefit is a package to estimate the extreme quantiles and probabilities of rare events. The idea of our approach is to adjust the tail of the distribution function over a threshold with a Pareto distribution. We propose a pointwise data driven pr

In this paper we consider the problem of restoration of a image contaminated by a mixture of Gaussian and impulse noises. We propose a new statistic called ROADGI which improves the well-known Rank-Ordered Absolute Differences (ROAD) statistic for de

Let $(Z_n)_{n\geq 0}$ be a critical branching process in a random environment defined by a Markov chain $(X_n)_{n\geq 0}$ with values in a finite state space $\mathbb{X}$ . Let $ S_n = \sum_{k=1}^n \ln f_{X_k}^{\prime}(1)$ be the Markov walk associat

International audience; In this paper we address the problem of denoising images obtained under low light conditions for the Poisson shot noise model. Under such conditions the variance stabilization transform (VST) is no longer applicable, so that t
