B5534 - COMPUTATIONAL IMAGING

Learning outcomes

At the end of the course the student knows about computational imaging methods and applications with a focus on solving inverse problems in imaging, such as denoising, deconvolution, single-pixel imaging, and others. He can solve some of the previous imaging problems by using both classic optimization algorithms and modern data-driven approaches with convolutional neural networks (CNNs).

Assessment methods

The exam consists of two parts:

1. Submission and discussion of a project assigned by the instructor at the end of the course. The discussion will take place through a presentation using slides or a notebook. The following will be evaluated:

• the correctness and efficiency of the software

• the accuracy of the results obtained

• the presentation

Maximum score: 25

1. A short oral exam on the theoretical topics covered in class (1–2 questions). The following will be evaluated:

• understanding of the topic

• clarity in the explanation of the topic

Maximum score: 6

Honors may be awarded at the discretion of the instructor.
