wird

Herr Dr. Klas Nordberg

(Computer Vision Laboratory, Linköping University, Sweden)

einen Vortrag halten zum Thema:

LIE GROUPS AND THEIR APPLICATION TO SIGNAL PROCESSING

Der Vortrag findet im Seminarraum der Gruppe VSI (Raum 317),
Robert-Mayer-Str. 2-4 (ehemaliges Physik-Gebäude, 3. Stock rechts)
statt.

 

Abstract:

The presentation shows how Lie groups can be applied to signal processing in general and in particular how mappings from signal to feature descriptors can be derived as solutions to a particular equation which describes the relation between transformations on the signal and the corresponding transformations on the descriptors. Examples from image processing and orientation estimation will be presented.

Part I: The concept of a Lie group is introduced in an intuitive way, and examples of such group are presented. The relation between a Lie group and its generators.

Part II: Introduction to tensor algebra. Book keeping and induced transformations.

Part III: Lie groups are applied to signal processing in general and in particular for orientation estimation in image processing. The concepts of invariance and equivariance are presented. The equivariance equation. Phase.

Part IV: Solving the equivariance equation for some simple examples in image processing.

Ich würde mich sehr freuen, Sie zu diesem Vortrag begrüßen zu dürfen.
