Notice

This module cannot be included in the Master's examination together with the module [MAT-65-10-M-4] or the module [MAT-65-14-M-7] due to large content overlaps. Students who have already used the course [MAT-65-10-K-4] for one of the specialization modules of the Bachelor's programme in Mathematics can use the second part of the course as module [MAT-65-14-M-7] "Distributions and Wavelets" for their master's studies.

Contents

From [MAT-65-12-K-7] Fourier Analysis with Applications in Image Processing:
  • Fourier series (Fourier coefficients and Fourier series, convolution of periodic functions, pointwise and uniform convergence of Fourier series, Gibbs phenomenon),
  • Fourier transform (Fourier transform in L1, Fourier transform in L2, Poisson’s summation formula and Shannon’s sampling theorem, Heisenberg’s uncertainty principle, Windowed Fourier transform),
  • discrete Fourier transform (approximation of Fourier coefficients and aliasing formula, Fourier matrix and discrete Fourier transform, circulant matrices, Kronecker products and stride permutations, discrete trigonometric transforms),
  • fast Fourier transform (Radix-2 algorithm, sparse Fourier transform, Fourier transform for non equispaced data),
  • Prony’s method for the reconstruction of structured functions (Prony method, recovery of exponential sums),
  • distributions (test functions and distributions, Schwartz spaces and tempered distributions, Fourier transform of tempered distributions),
  • wavelets and wavelet frames (continuous wavelet transform, wavelets frames, Haar wavelets, multiresolution analysis).

Competencies / intended learning achievements

Upon successful completion of this module, the students have studied and understand the basic problems and concepts of classical Fourier analysis, a branch of analysis with many practical applications. They have mastered the important and current techniques and are able to apply them to selected tasks in image processing. They understand the proofs presented in the lecture and are able to comprehend and explain them. In particular, they are able to outline the conditions and assumptions that are necessary for the validity of the statements.

By completing the given exercises, the students have developed a skilled, precise and independent handling of the terms, propositions and techniques taught in the lecture. In addition, they have learnt how to apply these techniques to new problems, analyze them and develop solution strategies individually or by team work.
