Phase-correlation based image registration
Druckmüllerová, Hana ; Martišek, Dalibor (oponent) ; Procházková, Jana (vedoucí práce)
This thesis deals with the use of phase correlation for estimation of mutual rotation, scale-change and translation between digital images. Phase correlation is based on the Fourier transform, therefore the thesis describes the Fourier transform of functions defined on R^2 and the discrete Fourier transform of functions defined on a finite number of points {0, 1, ... ,N-1}^2, where N is a natural number. The thesis describes modifications of the phase correlations for estimation of similarity transformation parameters between images with high dynamic range and faint structures, containing additive or impulse noise and images which are taken with different sensors and optical systems. The thesis also focuses on the modifications of the method used for registration of solar corona images taken during total solar eclipses, which counts among the hardest registration tasks.
