Linear filtering remains an attractive method of image recognition because of simplicity of its performance in standard computing systems. Moreover, even nonlinear procedures of image processing include, as a rule, linear filtering for preliminary se

In this paper we present the results of experimental investigation of wave-front distortion by amsotropic Te02 Bragg cellwith off-axial geometry. The measurements have been carried out using Shack-Hartmann wave-front sensor at visiblewavelength (O.63

In sight correction technologies, it is of extreme importance to know what outcome of the planned operation could be. Conventionally, cornea shape is measured, or even refraction distribution in the eye, that are used for calculations of the to-be-ab

A modified double-pass wave model is proposed being a wave diffraction model of the secondary coherent field formed due to double pass of light in the human eye system. The modification takes into account: cornea contribution into total eye refractio

Structural correlation analysis is carried out for 1D signals, represented as phase images. For LFM signals, mapped into generalized phase plane with coordinates x equals S, y equals S"/S, sensitivity of correlation analysis to staggering of deviatio

In this paper, we investigate the problem of optimal (feature) selection for texture recognition for the case, when statistical properties of the image general population are satisfactorally represented by the a prior classified training set of small

For superresolving image restoration it is suggested to use unsymmetrical matrix representation of image system's pulse response function in Karhunen-Loeve basis. Basic functions of such representation are defined by Karhunen-Loeve decomposition of o

Harnessing phased acoustic arrays for extending the operating range of optical deflectors is well known and investigated by a number of researchers. Usually, it was supposed, that acoustic waves are excited in contra-phase, or with phase difference l
