Contents:

Image analysis & processing deals with the investigation of images and the application of specific tasks on them, like enhancement, denoising, deblurring, and segmentation. In this course, mathematical methods that are commonly used are presented and discussed. The focus will be on the axiomatic choice for the models, their mathematical properties, and their practical use.

Course slides

Presentations:

...

Some key words:

Filtering (Edge detection, enhancement, Wiener, Fourier, ...)
Images & Observations: Scale space, regularisation, distributions.
Objects: Differential structure, invariants, feature detection
Deep structure: Catastrophes & Multi-scale Hierarchy
Variational Methods & Partial Differential Methods: Perona Malik, Anisotropic Diffusion, Total Variation, Mumford-Shah, Chan-Vese, geometric PDEs, level sets.
Curve Evolution: Normal Motion, Mean Curvature Motion, Euclidian Shortening Flow.

Audience:

As image analysis and processing is a mixture of several disciplines, like physics, mathematics, vision, computer science, and engineering, this course is aimed at a broad audience. Therefore, only basic knowledge of analysis is assumed and necessary mathematical tools will be outlined during the meetings.

Examination material:

Besides the slides that will e made available during the course, examination material exists of a collection of papers, covering the presented themes. For the Gaussian scale space part: For the non-linear part:

Examination:

Investigation and public presentation of recent work in image analysis (e.g. book chapter) provided at the course, and an written/oral exam on contents of the course (material & slides).
