Important Dates

Introductory meeting (mandatory):
Our introductory meeting took place on Wednesday, July 24, 2013, 16:15h, Building E1.7, Room 4.10.

Date of first regular meeting: Tuesday, October 29, 2013

Last meeting (planned): Tuesday, January 14, 2014

Write-up submission deadline: February 28, 2014, 12:00h pm (midday)

Description

Contents: In this seminar, we want to discuss interesting scientific papers from the field of image processing and computer vision. We will offer a balanced mixture between recent conference or journal publications and well-known, established concepts and methods.
The topics include but are not limited to image acquisition, image denoising and inpainting, sparse data representation, computer vision, optic flow and 3-D reconstruction.

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) is required, and some knowledge in image analysis is recommended.

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

Registration

You had to register for this course.

The registration period is over. You could register for this course
from Friday, July 19, 2013, 16:00h
to Tuesday, July 23, 2013, 15:15h.

Since the number of talks is limited, we ask for your understanding that participants had to be considered strictly in the order of registration – no exceptions.

Requirements for successful participation («Schein«)

Regular attendance: You must attend all seminar meetings, except for provable important reasons (medical certificate).

Talk: Talk duration is 30 min, plus 15 min for discussion. Please do not deviate from this time schedule.
You may give a presentation using a data projector, overhead projector or blackboard, or mix these media appropriately. Your presentation should be delivered in English. Your slides and your write-up, too, should be in English.

Write-up: The write-up has to be handed until Friday, February 28, 2014 12:00h pm (midday). The write-up should summarise your talk, about 5 pages per speaker will be adequate in most cases. Electronic submission is preferred. File format for electronic submissions is PDF – text processor files (like .doc) are not acceptable. Adhere to the standards of scientific referencing: Quotations and copied material (such as images) must be clearly marked as such, and a bibliography is required. Do not forget to hand in your writeup, because participants that do not submit a writeup cannot obtain the certificate for the seminar!

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!

No-shows: In case you do not appear to your scheduled talk, we reserve the right to exclude you from all 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. This participation is part of your final grade.

Being in time: To avoid disturbing or interrupting the speaker, all participants have to be in the seminar room in time. Participants that turn out to be regularly late must expect a negative influence on their grade.

Topics

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