Application of the fractional Fourier transform to image reconstruction in MRI

This Ph.D. dissertation is centered on the more “classical” applications of LS in the context of image coding: the analysis and improvement of existing wavelets as in §3.4.3 and

The guide includes a comparison to the windowed Fourier transform, the choice of an appropriate wavelet basis function, edge effects due to finite-length time series, and

This work describes the design and implementation of a new software framework, Scipion, that models image processing in electron microscopy allowing the integration of several

The algorithm uses a parametrical model to generate the synthetic Discrete Fourier Transform (DFT) of the trajectory signals, which are then refined in the time domain and completed

A simple method to alleviate this problem consists of multiplying the pro- jection Fourier transform by the sign of the CTF (this approach is named phase flipping (Frank, 1996,

We first Fourier transform the whole real space image (shown in figure 1(a)), center the resulting Fourier image at the peak corresponding to CDW’s component with highest amplitude

Since the objective of a fusion method is to simulate a target image at a given date, in order to perform the validation it was necessary to generate fused images at target dates
