Image restoration using a multilayer perceptron with a multilevel sigmoidal function

Abstract

The problem of restoring a blurred and noisy image having many gray levels, without any knowledge of the blurring function and the statistics of the additive noise, is considered. A multilevel sigmoidal function is used as the node nonlinearity, due to which the same number of nodes as in the case of a binary image is suucient for an image with multiple… (More)
