Contents: Inpainting has been introduced as a technique to restore missing or deteriorated regions by using information from within the image. There are various ways to fill these missing parts such as simple interpolation, diffusion-based methods, or by comparing image patches. Nowadays, specialised inpainting methods can remove objects seamlessly or can even reconstruct an image using only a tiny fraction of the original information. In this seminar, we firstly cover basic concepts and move on to forefront research in the field of inpainting.

Prerequisites: The seminar is for advanced bachelor or master students in Visual Computing, Mathematics, or Computer Science. Basic mathematical knowledge (e.g. Mathematik für Informatiker I-III) and some knowledge in image processing and computer vision is required.

Language: All papers are written in English, and English is the language of presentation.


You must register for this course via the Seminar System

from September 26, 2022
until October 26, 2022
.


Regular attendance: You must attend all virtual seminar meetings. If you are sick, please send a medical certificate via mail to Kristina Schaefer. If you have technical difficulties, let us know as soon as possible.

Talk: Talk duration is 30 min, plus 15 min for discussion. Please do not deviate from this time schedule. It will be performed in a virtual setting. More details and a best practice guide will be made available after the introductory meeting.

Write-up: The write-up has to be handed in three weeks after the lecture period ends. The deadline is TBD. The write-up should summarise your talk and has to consist of 5 pages per speaker. Please adhere to the guidelines for write-ups posted in our Teams group. Submit your write-up in pdf format directly in the corresponding assignment in Teams.

Plagiarism: Adhere to the standards of scientific referencing and avoid plagiarism: Quotations and copied material (such as images) must be clearly marked as such, and a bibliography is required. Otherwise the seminar counts as failed. See the write-up guidelines for a detailed explanation on how to cite correctly.

Mandatory consultation: Talk preparation has to be presented to your seminar supervisor no later than one week before the talk is given. It is your responsibility to approach us timely and make your appointment for a video call.

No-shows: No-shows are unfair to your fellow students: Some talks are based on previous talks, and your seminar place might have prevented the participation of another student. Thus, in case you do not appear to your scheduled talk (except for reasons beyond your control), we reserve the right to exclude you from future seminars of our group.

Participation in discussions: The discussions after the presentations are a vital part of this seminar. This means that the audience (i.e. all paricipants) poses questions and tries to find positive and negative aspects of the proposed idea.

Being on time: All participants have to be in the seminar meeting on time. Participants that turn out to be regularly late must expect a negative influence on their grade.



We will discuss the following papers. If your registration was successful, the password will be sent to you before the first meeting.
