Image blurring process is commonly formulated as two-dimensional convolution between the latent image and the blurring system. Blind image restoration problem is to estimate the latent image only from the blurred image. Conventional blind image restoration techniques tend to solve this problem by estimating the blurring system and therefore their effectiveness are dependent to the accuracy of t...

The eld of image restoration lacks promising comparison vehicle for judging the e ectiveness of competing algorithms. By far the most widely adopted quantitative measurement of image restoration performance is by means of the SNR improvement. In this paper we address the issues on performance assessment of image restoration and propose a uni ed framework for the performance measure. The SNR imp...

The one-dimensional version of the higher order total variation-based model for image restoration proposed by Chan, Marquina, and Mulet in [4] is analyzed. A suitable functional framework in which the minimization problem is well posed is being proposed and it is proved analytically that the higher order regularizing term prevents the occurrence of the staircase effect.

Floodplain restoration projects are part of sustainable flood management model. However, in practice, they are rarely implemented. We analyze the failure of a floodplain restoration project that was supposed to be implemented on the River Rhône (France). Based on the analysis of floodplain restoration projects implementation literature, we identified several constraints on the implementation of...

This paper presents a new filtering approach based on fuzzy-logic which has high performance in mixed noise environments. This filter is mainly based on the idea that each pixel is not allowed to be uniformly fired by each of the fuzzy rules. In the proposed filtering algorithm, the rule membership functions are tuned iteratively in order to preserve the image edges. Several test experiments we...
