Course Information
About
This advanced undergraduate course is about the fundamentals of computational photography, an emerging new research area which brings together the advancements in computer graphics, computer vision and image processing to overcome the limitations of conventional photography. The course is structured around basic topics such as cameras and image formation, high dynamic range imaging, edge-aware filtering, gradient-domain processing, deconvolution, blending and compositing, visual quality assessment, deep image enhancement, neural rendering.
The main goal of this course is to introduce students a number of different computational techniques to capture, manipulate and enrich visual media. The students are expected to develop a foundational understanding and knowledge of concepts that underly computational photography. The students will also be expected to gain hand-on experience via a set of programming assignments supplied in the complementary practicum.
The course is taught by Erkut Erdem, and the teaching assistant is Orhan Demirci.
Time and Location
Lectures: Mondays at 09:40-12:30 (D9)
Practicum: Mondays at 16:40-17:30 (D8)

Policies: All work on assignments must be done individually unless stated otherwise. You are encouraged to discuss with your classmates about the given assignments, but these discussions should be carried out in an abstract way. That is, discussions related to a particular solution to a specific problem (either in actual code or in the pseudocode) will not be tolerated.
In short, turning in someone else’s work, in whole or in part, as your own will be considered as a violation of academic integrity. Please note that the former condition also holds for the material found on the web as everything on the web has been written by someone else.
Communication
The course webpage will be updated regularly throughout the semester with lecture notes, presentations, assignments and important deadlines. All other course related communications will be carried out through ed. Please enroll it by following the link https://edstem.org/eu/join/aQPP8t.
Pre-requisites
Good math (calculus, linear algebra, statistics) and programming skills. An introductory course in image processing (BBM413/AIN430), and/or computer vision (BBM416/AIN431) and/or machine learning (BBM406/AIN311) is highly recommended.
Course Requirements and Grading
Grading for BBM444/AIN434 will be based on
- Class participation (5%),
- Course project (done in pairs) (30%),
- Midterm exam (30%), and
- Final exam (35%).
Grading for AIN435/BBM446 will be based on
- Four assignments (done individually) (25% each).
