Description

ECE 395/495: Computational Photography Seminar

Winter 2020; T/Th 3:30pm – 4:50pm

Course Coordinator: Ollie Cossairt 

Course Goals and Description

This course is second in a two-part series that explores the emerging new field of Computational Photography. Computational photography combines ideas in computer vision, computer graphics, and image processing. This course will introduce state-of-the-art topics in computational photography such as 3D imaging, light fields, holographic displays and much more!

Covered topics are:

  • Topic 1: Ray Optics, Bright/Dark Field, Phase Contrast and Schlieren Imaging
  • Topic 2: Active and Passive Triangulation, Structured Light 3D imaging
  • Topic 3: Light field imaging, Plenoptic Representations, Aperture Synthesis
  • Topic 4: Appearance capturing and Photometric Stereo
  • Topic 5: Time-of-Flight imaging, Imaging Around Corners and through Scatterers
  • Topic 6: 3D Imaging of Specular Objects, Deflectometry
  • Topic 7: Event Cameras, Motion Processing
  • Topic 8: Interferometry, Holography, Lensless Imaging
  • Topic 9: Light Transport, Direct and Global separation
  • Topic 10: Extended Depth of Field, Super-Resolution
  • Topic 11: Light field Displays and Holographic Displays
  • Topic 12: Computed Tomography 

Students can pick one topic to work on in groups of 2 or 3. Each student will pick one research paper related to the chosen topic that will be introduced by the student in a brief 15-20 minute presentation. Potential research papers to present will be posted on the course website. The presentation will be given in class, followed by a short discussion that is led by the student.

Additionally, each group working on a topic together will implement a final research project. The project can be related to the chosen topic (e.g. building a structured light 3D scanner, capture and render a lightfield, build your own 3D display, …), but does not have to. Resources will be provided to assist students in their research projects (e.g. SLR cameras, lenses, light field cameras, projectors, etc.). Ideas for potential projects will be posted on the course website. Project proposals will be due in the middle of the course, and the final results for the project will be presented in the final day of class. For the presentation of their research project, each group will have to prepare a poster that describes the key findings and achievements. 

Grading

Course assignments will consist of a paper presentation and a final research project. There will be no midterm or final exam.

  • Paper Presentations and Discussions - 50%
  • Final Project – 50%

Texts

There will be no text, readings will be posted on the course website
