Computer Vision (in Englisch)
Typ: Hauptstudium / Vertiefungslinie
Semester: WS 2013/2014
Umfang: 3V+1Ü
Studiengang: Diplom Informatik, Diplom Softwaretechnik, Master Informatik, Master Softwaretechnik
Dozent: Prof. Dr.-Ing. Andrés Bruhn
Beschreibung:

This class gives an in-depth introduction into the field of computer vision. It consists of four parts. In the first part, characteristic image features and feature descriptors are discussed that are typically used for recognition or matching, The second part of the course is dedicated to motion and stereo. Fundamental goals in this context are the recovery of the 3-D structure and the 2-D motion of objects from a recorded scene. The third part of the class is dedicated to segmentation - the subdivision of an image into different semantically meaningful regions. Here, the focus lies on contour based methods that are among the leading techniques in the field. Finally, the fourth part deals with pattern recognition the classification of features into different groups. In this context, basic approaches for the reducing the dimensionality of features and strategies for supervised learning are discussed.

This class requires undergraduate knowledge in mathematics (e.g. ''Mathematik für Informatiker und Softwaretechniker", "Numerische und stochastische Grundlagen der Informatik"). The previous attendance of the class "Imaging Science" is recommended. Lectures will be in English.


This class is particularly useful for those students who wish to pursue a bachelor, master or diploma thesis in our group.

REMARKS:

  • The programming exercises are designed for Linux. We only guarantee that the code works under Linux.
  • If possible, we will provide executables for Windows. You may use them at your own risk.
  • At some points we may have to provide object files for copyright reasons. Object files will only be provided for Linux.
  • If there are any problems reading in and writing out files under Windows, adding the binary flag may help, i.e. inimage = fopen(in,"rb");
