Paper Abstract

A novel technique for digital image halftoning is presented, performing nonstandard quantization subject to a fidelity criterion. Massively parallel artificial symmetric neural networks are used for this purpose, minimizing a frequency weighted mean squared error between the continuous-tone input and the bilevel output image. The weights of these networks can be selected, so that the generated halftoned images are of good quality. A symmetric formulation of the error diffusion halftoning technique is also presented in the form of a massively parallel network. This network contains a nonmonotonic nonlinearity in lieu of the sigmoid function and is shown to be appropriate for effective halftoning of images.
