Content, Learning Outcome and Preconditions

Content

Variational Methods are among the most classical techniques for optimization of cost functions in higher dimension.
Many challenges in Computer Vision and in other domains of research can be formulated as variational methods.
Exemples include denoising, deblurring, image segmentation, tracking, optical flow estimation, depth estimation from stereo images or 3D reconstruction from multiple views.
In this class, the basic concepts of variational methods will be introduced :
- The Euler-Lagrange calculus and partial differential equations
- Formulation of computer vision and image analysis challenges as variational problems
- Efficient solution of variational problems
- Discussion of convex formulations and convex relaxations to compute optimal or near-optimal solutions in the variational setting
The key concepts will be implemented in Matlab to provide hands-on experience.

Learning Outcome

Upon successful completion of the module the participants understand the basic concepts of variational methods on a fundamental, scientific and practical level.
They are able to efficiently solve variational problems and to implement the solution with Matlab.

Preconditions

MA0901 Linear Algebra for Informatics
MA0902 Analysis for Informatics

Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

The main concepts will be presented in the lecture. During the tutorial, related exercises and discussions will deepen the understanding. Besides theoretical exercises, there will be programming exercises.

Media

Tutor presentation, interactive problem solving, discussion

Literature

Mathematical Image Processing (Bredies, Lorenz)

Module Exam

Description of exams and course work

The exam takes the form of a 120 minutes written test. In the written exam students should prove that they understood the basic concepts of variational methods. The questions will focus on the key concepts which have been discussed during the lecture and the tutorials. Mathematical proofs of the central concepts and questions about the implementation in Matlab assess acquaintance with the concepts in variational image processing.

Exam Repetition

The exam may be repeated at the end of the semester.

Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
