Application of spectral and spatial processing methods to sonar images

Autor: A. V. Kokoshkin, E. P. Novichikhin, Ilia V. Smolyaninov

Publikováno v: Radioelectronics. Nanosystems. Information Technologies.. 13:377-382

The paper proposes the use of the method of renormalization with limitation (MRL) for suppressing the speckle noise of images obtained using sonar. The method is tested on real images obtained by the interferometric side-view sonar. The principal pos

Restoring Missing Fragments of a Distorted Image Due to Defocusing or Blur of a Known Hardware Function

Autor: E. P. Novichikhin, A. V. Kokoshkin

Publikováno v: Radioelectronics. Nanosystems. Information Technologies. 12:495-506

In this paper, a comparative analysis of the methods for recovering images distorted by defocusing or blurring from incomplete data is performed using examples. Incomplete data means the absence of any image fragments that were retouched using differ

Reconstruction of Acoustic Signals According to Incomplete Data

Autor: E. P. Novichikhin, A. V. Kokoshkin, V. A. Korotkov

Publikováno v: Journal of Communications Technology and Electronics. 65:1399-1406

Problems of reconstructing acoustic signals from unevenly spaced samples (sparse signal) and signals distorted by losses of adjacent samples (solid gaps) are considered. To solve these problems original algorithms are proposed: the Interpolation Meth

Autor: A. A. Milshin, E. P. Novichikhin, N. K. Shelobanova, A. G. Grankov

Publikováno v: Journal of Communications Technology and Electronics. 65:1122-1128

—The paper presents examples of satellite radiometric microwave measurements to analyze the atmospheric moisture content during the development of tropical hurricanes at the initial stages and during propagation from their origination zones, as wel

Retouching and restoration of missing image fragments by means of the iterative calculation of their spectra

Autor: E. P. Novichikhin, V. A. Korotkov, A. V. Kokoshkin, Kirill Korotkov

Publikováno v: Компьютерная оптика, Vol 43, Iss 6, Pp 1030-1040 (2019)

This paper discusses the use of the interpolation method for the sequential calculation of the Fourier spectrum (IMSCS) for retouching and restoration of missing (shaded) image fragments. The proposed approach can be used with any form of a missing i

Determination of Average Monthly Heat Fluxes in the North Atlantic from EOS Aqua AMSR-E Radiometer Data

Autor: A. G. Grankov, A. A. Milshin, E. P. Novichikhin

Publikováno v: Russian Meteorology and Hydrology. 44:523-528

The potential of using data of long-term AMSR-E (EOS Aqua satellite) microwave radiometer measurements for the determination of heat fluxes in the North Atlantic energy active zones in 2003–2011 is investigated. It is shown that there is a direct (

Publikováno v: Journal of Communications Technology and Electronics. 64:569-580

—A new approach to solving the problems reconstructing images distorted by defocusing and blurring is proposed. It is shown that for an alternating amplitude spectrum of the hardware function (HF), the renormalization method with constraint (RMC) w
