Announcements

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 first written exam will take place on Thursday, February 18, 2010 from 2:00 to 4:00 pm in building E1.3, lecture hall 002.
The second exam will take place on Tuesday, March 30, 2010 from 2:00 to 4:00 pm in building E1.3, lecture hall 002.
These are closed book exams. If you have been registered for this class, you may participate in both exams, and the better grades counts.

The grades for the second written exam are now available!

The following thresholds were applied to determine the grades:

1.0 : 30 - 28 points
1.3 : 27 - 27
1.7 : 26 - 25
2.0 : 24 - 24
2.3 : 23 - 22
2.7 : 21 - 21
3.0 : 20 - 19
3.3 : 18 - 18
3.7 : 17 - 16
4.0 : 15 - 14
5.0 : 13 - 0

The detailed distribution of points was:

24 points : 1
23 points : 1
22 points : 1
20 points : 2
18 points : 2
17 points : 4
16 points : 2
14 points : 3
11 points : 2
03 points : 1

The results can be queried via our online query form.

You can inspect your exam sheets on Friday, April 9, 14:00-15:00, building E1.1, room 3.06 (3rd floor).

NEWS: The cerfificates (Scheine) are issued by the office of the Mathematics Department. They can be obtained from Ms. Voss, Building E2.4, Room 111 (math building, ground floor, 8.15-11.30 AM).
