VYF Acad. year 2022/2023 Summer semester 5 credits
Current digital cameras almost completely surpass traditional photography. They do not only capture light, they in fact compute pictures. That said, there is practically no image that would not be computationally processed to some extent today. Visual computing is ubiquitous. Unfortunately, images taken by amateur photographers often lack the qualities of professional photos and some image editing is necessary. Computational photography (CP) develops methods to enhance or extend the capabilities of the current digital imaging chain.

The aim is to introduce computational photography methods (http://cphoto.fit.vutbr.cz/) and to get acquainted with the principles of mathematics and computer science in the field.
Why is the course taught
Computational photography techniques are placed at boundaries of image processing, computer vision, physics, visual perception and other fields. The course is offering a holistic view of this intersection, while many principles are demonstrated practically during lectures (photography, HDR acquisition, tone mapping, image registration, spherical panoramic imaging, etc.). Students may take part in photographic challenges and get a valuable feedback from their colleagues and tutors. Prior knowledge of computer vision, graphics or image processing is beneficial, but not required.

It is obligatory to be present at the written exam, submit the project including textual report and oral presentation. At least 50 points must be obtained, while the minimal score from the test is 16 points, the minimal score from the project is 24 points. During the term, one can get bonus points in practical photography challenges.
