Analysis of Linear Distortion Characteristics in Problems of Restoration of Multispectral Images

Abstract

Available methods for restoration of degraded multispectral images often use the linear distortion model. These distortions can be due to technical characteristics of imaging systems, environmental conditions of signal detection, and motion of the recording camera or the object. In order to efficiently restore a degraded image, it is necessary to analyze the distorting operator. The analysis includes both the way of determining the distortion type and estimation of the operator parameters. In this paper, a method for the analysis of the linear distorting operator by the spectrum of the degraded image is proposed. Using computer simulation, specific features of distortions in the spectra of test multispectral images caused by the impact of typical linear operators are illustrated.
