Announcements

Exam results have been sent to all participants of the written exam by personal mail. If you have not received this mail, please contact Martin Welk.
Inspection of written exam sheets is possible on Thursday, March 15, 2007, 1400–1500h (2–3 p.m.) in Martin Welk's office, or at other times on appointment.
Second chance exams for those who failed the first exam, or who did not take part in the first exam, will be held as oral exams, on individual appointment, preferably on April 12. Those who failed the first exam have already been communicated their scheduled exam time by e-mail. If you have not received an e-mail concerning your exam time, please contact Martin Welk immediately! Other registered course participants who have not taken the first exam, please contact Martin Welk till April 3 if you want to appoint a second chance exam.

Description

The course is designed as a supplement for image processing lectures, to be attended before, after or parallel to them.

Participants shall understand

what are digital images
how they are acquired
what they encode and what they mean
which limitations are introduced by the image acquisition.

This knowledge will be helpful in selecting adequate methods for processing image data arising from different methods.

Entrance requirements

Basic mathematics courses are recommended. Understanding English is necessary.

Contents

A broad variety of image acquisition methods is described, including imaging by virtually all sorts of electromagnetic waves, acoustic imaging, magnetic resonance imaging and more. While medical imaging methods play an important role, the overview is not limited to them.

Starting from physical foundations, description of each image acquisition method extends via aspects of technical realisation to mathematical modelling and representation of the data.

Assessments / Exams

The written exam took place on Monday, February 26, 2007, 9–11; in Lecture Hall 001, Building E13.
Students registered for the course were automatically registered for the exam, unless signed out by e-mail till February 12, 2007, 9:00h (9 am).

Students who cannot take part in the written exam for substantial reasons, and those who have failed the written exam, will be offered oral exams, to be appointed individually.
