Winter Term 2019 / 2020
Lecture with Exercises (3+1SWS)
Language: English

Lecture: Wednesday, 11:30 - 13:00, Computer Science Building, Lecture Hall V38.03.
Lecture: Friday, 9:45 - 11:15, Computer Science Building, Lecture Hall V38.03 (bi-weekly).
Exercises: Friday, 9:45 - 11:15, Computer Science Building, Lecture Hall V38.03 (bi-weekly).

NEWS: Change of lecture hall: The lecture on Wednesday, November 13 takes place in room V57.06 (Pfaffenwaldring 57). The time slot (11:30 - 13:00) remains the same.

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 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 or master thesis in our group.

All course material (lecture notes, assignments, code, example solutions) are available in the ILIAS system.
