Overview

The course provides a detailed and mathematically precise introduction to Fourier, Wavelet and multiresolution analysis from a computational point of view. This includes algorithmical aspects, complexity analysis, and exemplary applications relevant to scientific and visual computing.

Goals and Objectives

The course is algorithmically oriented aiming to enable the students to develop principled computational methods for problems related to Fourier, Wavelet and multiresolution analysis.

Required Knowledge

The course will assume solid knowledge (calculus and linear algebra) such as taught in undergraduate mathematics courses or in AMCS 101, 131, and 151.

Assignments and Evaluation

There will be a problem set assigned each week to prepare for the final exam. This homework track is mostly theoretical, but it will include smaller programming tasks along the way. The students may collaborate on the assignments. Grading policy: 100% final exam.
