Registration for this lecture was open until Thursday, Oct 26. Keep in mind that in most courses of studies, you also have to register via the HISPOS system of the Saarland University

In this lecture, we will discuss advanced topics in the fields of image processing and computer vision. Most of the presented methods fuse the information from several images in order to produce an enhanced composite image. Examples for such techniques are super-resolution, high dynamic range (HDR) imaging, tone mapping and gradient domain techniques.

Example: Freehand High Dynamic Range Imaging

Exposure series	Tone mapped HDR reconstruction without and with alignment

Requires undergraduate knowledge in mathematics (e.g. ''Mathematik für Informatiker I-III''), and elementary C knowledge. Basic knowledge in image processing and computer vision is recommendable. The lectures and tutorials will be given in English.

In order to qualify for the exams, attendance of the tutorials is mandatory. You will not be allowed to take part in the exams if you miss more than two tutorials. In case of qualification, you are allowed to take part in both exams. The final grade will be the best grade out of the two exams. There will be two closed book written exams:

The first written exam will take place on Friday, February 2, 2018 from 2:00 to 4:00 pm in Building E1.3, Lecture Hall 002.
The second written exam will take place on Tuesday, April 3, 2018 from 2:00 to 4:00 pm in Building E1.3, Lecture Hall 002.
These are closed book exams. You can participate in both exams, and the better grades counts.

Please remember that you have to register online for the exam in the HISPOS system of the Saarland University.

If you cannot attend the exam, contact Pascal Peter as early as possible. In case you have proof that you cannot take part for medical reasons or you have another exam on the same day, we can offer you an oral exam as a replacement. Note that we need written proof (e.g. a certificate from a physician/Krankenschein) for the exact date of the exam.

These are the rules during the exams:

• No lecture materials are admitted during the exam.
• Pocket calculators are not allowed.
• Mobile phones, PDAs, laptops, smart watches, and other electronic devices have to be turned off.
• Please keep your student ID card ready for an attendance check during the exam.
• Do not write solutions with pencils or friction pens.
• You are not allowed to take the exam sheets with you.
• You must stay until the exam is completely over.

Participants can download course materials (lecture notes, assignments) here. For all assignments, example solutions will be provided. Additional organisational information, examples and explanations that may be relevant for your understanding and the exam are provided in the lectures and tutorials. It is solely your responsibility - not ours - to make sure that you receive this infomation.
The table below contains the planned topics for the lecture. The slides are available in two versions: the "script" version is printer friendly while the "slide" version retains the functionality to enlarge images and use slide navigation.

Each week we have either a theory or a programming tutorial. They take place in:

Monday 16-18 c.t.
Building E1.3, Seminar Room 016 (theory)
Building E1.3, CIP 104 (programming)

Programming excercises and theoretical assignments are offered as part of the tutorials. The regular attendance of these tutorials is required for the admission to the exam. You will not be allowed to take part in the exam if you miss more than two tutorials.

The assignments and the source code needed for the programming assignments will be provided here during the semester.

There is no specific book that covers the complete content of this class. Many lectures will be based on articles from journals and conferences. However, the recent book of R. Szeliski covers some of the topics and additionally summarises most of the intensively studied areas of computer vision research:

R. Szeliski: Computer Vision: Algorithms and Applications.
ISBN: 978-1-84882-934-3, Springer, Berlin, 2011.
