Statistical mechanics of image restoration and error-correcting codes.

We develop a statistical-mechanical formulation for image restoration and error-correcting codes. These problems are shown to be equivalent to the Ising spin glass with ferromagnetic bias under random external fields. We prove that the quality of restoration/decoding is maximized at a specific set of parameter values determined by the source and channel properties. For image restoration in a me...

Image Restoration Using Statistical Wavelet Models

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 ...

Some Aspects of Statistical Image Modelling and Restoration

A review is provided of some ways in which statistical ideas have influenced research into image analysis, in particular the problems involved in making inferences about the true scene and any parameters in the underlying model. The emphasis will be on the application of general statistical paradigms such as maximum likelihood, implemented using tools such as the EM algorithm, and Bayes’ Theore...

Image Restoration Using A PDE-Based Approach

 Image restoration is an essential preprocessing step for many image analysis applications. In any image restoration techniques, keeping structure of the image unchanged is very important. Such structure in an image often corresponds to the region discontinuities and edges. The techniques based on partial differential equations, such as the heat equations, are receiving considerable attention i...

Statistical image restoration based on adaptive wavelet models

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