Seminar: Methods and Algorithms for Image Segmentation

Seminar: Methods and Algorithms for Image Segmentation
SS 09

The Chair of Pattern Recognition and Image Processing offers in SS09 a seminar with the title "Methods and Algorithms for Image Segmentation".

Motivation and Aim:

Segmentation is the partitioning of a digital image into multiple regions, according to some creterion. It builds the threshold between low-level image processing and higher-level analysis and is perhaps the most challenging of all image operations. Depending on the application, image segmentation can base purely on gray values or already make use of prior knowledge about the structures to be segmented.
Diverse approaches to segmentation will be covered in this seminar. you will have a chance to understand the basic ideas behind each approach and to concentrate on one topic and implement the corresponding algorithm. The implementation will be tested on database. Results will be discussed and interpreted.

Workflow:

*	During the "Vorsprechung", topics will be bindingly distributed and presentation dates will be fixed.
*	An introduction talk on image segmentation will be given in the week following.
*	Each participant should give an oral presentation of 45 minutes on his topic.
*	The algorithms shall be implemented and tested on database. Results will be discussed and interpreted.
