1. Using a stochastic basis in signal and image recovery problems.

Author

Batishchev, V., Volkov, I., and Zolin, A.

Abstract

This paper touches upon the problems of constructing a basis for stochastic functions, which represent samples of random numbers with a given distribution law. The algorithm for constructing an approximation model with the use of this basis is described. The general algorithm for signal recovery using the stochastic basis by the least squares method with a given weight function is given. The approach to solving the problem of recovery of blurred images with a known point scattering function by constructing an inverse filter model is proposed. [ABSTRACT FROM AUTHOR]

2. SHARPNESS CORRECTION MODERNIZATIONS ON COSMIC HIGH RESOLUTION IMAGES

Author

Vintaev, V.N. and Ushakova, N.N.

Subjects
generalized function with zero measure carrier, spatial frequency spectrum, Lebesgue integral, problem-oriented computer arithmetic, point scattering function, space image, deconvolution
Abstract

Processing of cosmic images is considered with the replacement of singularities arising in the synthesis of spectral representations by models of generalized functions of slow growth, using problemoriented computer arithmetic that supports the completeness of operations during deconvolution to increase sharpness.
