Computersehen: Einführung

The resit will take place in an oral format (online).

Applied Computer Science: Please register via FlexNow until 29th of January.
All other subjects: To register, please send an e-mail to the lecturer by 29th of January, stating your name, matriculation number, and subject.

In order to receive an individual exam appointment, please send a request to no later than 10th of February. You will receive an appointment suggestion in return which can be adapted, if necessary.


Online Course Format

Screencasts of each lecture will be made available in the moodle course at the originally scheduled lecture times.

Excercise sheets will be made available shortly after. They include both argumentative and programming tasks, which will be discussed during online meetings in the week following the assignments. 

Students are asked to go through the course material (lectures and excercises) and prepare presentations of their solutions to the given problems, e.g. by sharing their computer screen to explain code.

For further details on the procedure, see the moodle course.



Course Topics

The lecture introduces students to the fundamentals of digital image processing. The effect of different methods and procedures is demonstrated with examples from several fields of application (e.g. medicine, robotics, driver assistance systems).

Some of the topics that are covered:

  • What are digital images?
  • Histograms - Point operators (contrast equalization, thresholding, histogram equalization)
  • Filters (Box filter, Gaussian filter, low pass and high pass filters, median filter, edge filter)
  • Hough transform
  • Morphological operators
  • Geometrical image operations
  • Interpolation
  • Segmentation
  • Classification
  • Viola-Jones framework

The lectures will be given in German.

The Institut für Neuroinformatik (INI) is a central research unit of the Ruhr-Universität Bochum. We aim to understand the fundamental principles through which organisms generate behavior and cognition while linked to their environments through sensory systems and while acting in those environments through effector systems. Inspired by our insights into such natural cognitive systems, we seek new solutions to problems of information processing in artificial cognitive systems. We draw from a variety of disciplines that include experimental approaches from psychology and neurophysiology as well as theoretical approaches from physics, mathematics, electrical engineering and applied computer science, in particular machine learning, artificial intelligence, and computer vision.
