The Point Spread Function of an Aperture in the Form of Corona Virus (COVID 19) Images
Hamed, Abdallah;
Abstract
In this paper, an aperture in the form of Coronavirus is suggested. Two models are given to represent the aperture where the circular part has linear distribution in both models and is surrounded by eight equal circles of minimal diameter. The small circles, in the 1st model, has linear distribution while in the 2nd model, Hamming distribution is assumed. The Point Spread Function PSF is computed in both models and compared with the PSF in the case of uniform aperture. The Fourier spectrum of COVID-19 is calculated and plotted. In addition, the autocorrelation is computed in all cases and compared with the autocorrelation function corresponding to the Coronavirus image. The Mat-Lab codes are used in the computation of all images and plots.
