Computational Photography

FIT-VYFAcad. year: 2024/2025

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.

Exam prerequisites

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.

Aims

Methods of computational photography stand at the border of image processing, computer vision, computer graphics, physics, visual perception and other fields. The course offers the student a comprehensive view of this intersection, while a number of principles are demonstrated practically directly during the lectures (classical photography, HDR acquisition, tone mapping, image registration, spherical panoramic images, etc.). Students have the opportunity to participate in photo challenges and receive feedback from peers and lecturers. Previous knowledge of taught subjects on computer vision, graphics, or image processing is an advantage, but not required.
