Image Processing and Computer Graphics

Prof. Thomas Brox, Prof. Matthias Teschner

Image Processing and Computer Graphics are fields in computer science which have shown a steady growth in the last two decades. They have impact not only in computer science but also in other research areas, such as biology or medicine. Image processing is quite important in robotics and many industrial applications. Computer graphics dominates the movie theaters. Many tools from mathematics and machine learning influence research in image processing and computer graphics. This makes it a very diverse research field.
This course gives a broad overview of these fields and introduces the basic techniques. It is highly recommended to take this course before attending other classes in computer vision or computer graphics. Consequently, if you think about specializing in these fields, you should take this course as early as possible. The exercises are intended to give you a better understanding of the most important techniques you learn in class. You are supposed to implement some selected methods in C/C++ and develop an intuition of their usage.

Due to the Corona pandemics, the complete course on Image Processing will be provided as online course. This includes both the lectures and the exercises. You can find all lectures below for download. They have been recorded last year. There will be multiple dates, where you can ask questions via teleconference. For the exercises there will be a discussion forum that you can use to ask questions and interact with the advisors. Register once for the course in ILIAS.
You can do large parts of the course asynchronously, such that it fits best your available time. Only for the video conferences that are attended by multiple students, we synchronize. It is assumed that you have watched all the recordings set before the video conference date and also your questions are only about the material that you were supposed to watch up to then.

For details on the Computer Graphics part, please refer to the site of Prof. Teschner

Recordings are about 250MB each; some are much bigger due to videos. The German recordings are pretty old. Preferably use the English ones.


There is a forum for discussion.
