The development results of a telescopic system that allows high-quality digital images of distant objects to be obtained in horizontal routes with a high spatial resolution, which in an extreme case tends toward the diffraction limit, are reported in

This paper discuses the problem of reconstructing images in digital form with resolution that exceeds the limiting resolution of a diffraction-limited system from a set of images with spatially modulated illumination. The reconstruction method descri

New computational technique based on linear-scale differential analysis (LSDA) of digital image is proposed to find the best focus position in digital microscopy by means of defocus estimation in two near-focal positions only. The method is based on

A novel method of sharpness improvement is proposed for digital images. This method is realized via linear multi-scale analysis of source image and sequent synthesis of restored image. The analysis comprises the procedure of computation of intensity

The model of contrast sensitivity function (CSF) of machine vision system, based on the CSF of the human visual system is proposed. By analogy with the human eye, we employ the concept of ganglion cell receptive field to the artificial light-sensitiv

Research on the nonlinear refractive indices of solid dielectric active media is reviewed. The review is restricted to media for which the nonlinear refractive index is fast, i.e., has a relaxation time τ < 10−9 s. The nature of the nonlinear refr

Based on a representation of the receptive fields of the human retina, a mathematical model has been developed that describes the primary stage of the processing of visual information, taking into account the internal noise of the photoreceptors. The
