Computational Photography (WS2007)

0433 L 380
Instructor:
Prof. Dr. Marc Alexa
Contact

Dr. Olga Sorkine

Course structure:
Seminar (SE) - 2 SWS
Room:
EN 719
Date:
Dienstag   16:00  -  18:00    wöchentl
Beginn : 16.10.2007
Description:
Syllabus:
Computational photography extends the possibilities of classical photography by postprocessing several digital images of the same objects taken with different camera parameters. The course gives a brief overview of the basic ideas and several recent developments. Then students are expected to implement a technique discussed in the literature or their own ideas (at the discretion of the instructor). The ideas and resulting images are presented in a final talk.
Comments:
Grading will be based on implementation and the talk.

Prerequisites:
Programming skills, ideally access to a digital camera (although this could be arranged for a limited number of participants), interest in visual arts/photography.

Front Matter

  • Preferred language: english (although communication clarity wins over this language preference)
  • Attendance is mandatory
  • Please make use and reuse all available resources (but give references)
  • Grading will be based on all aspects of performance
