Restoring Poissonian noise images have drawn a lot of attention in recent years. There are many regularization methods to solve this problem and one of the most famous methods is the total variation model. In this paper, by adding a quadratic regularization on TGV regularization part, a new image restoration model is proposed based on second-order total generalized variation regularization. The...

This paper presents a probabilistic safety assessment framework based on the international standard, IEC 61508, for control laws designed especially by reliable control theory. The framework uses Markov techniques summarized in IEC 61165 to take restoration of devices into consideration. It clarifies a contribution of reliable control to risk reduction required in IEC 61508. Copyright c ©2005 IFAC

In this paper, we propose an image restoration algorithm based on state-of-the-art wavelet domain statistical models. We present an efficient method to estimate the model parameters from the observations, and solve the restoration problem in orthonormal and translation–invariant (TI) wavelet domains. Substantial improvements over previous wavelet–based restoration methods are obtained. The use ...

The practice of ecological restoration is a primary option for increasing levels of biodiversity by modifying human-altered ecosystems. The scientific discipline of restoration ecology provides conceptual guidance and tests of restoration strategies, with the ultimate goal of predictive landscape restoration. I construct a conceptual model for restoration of biodiversity, based on site-level (e...
