Homework:
Please follow this link to access the homework details. Homework details/materials are accessible only within Bilkent network. Use VPN to access from home.

Literature Survey and Presentation:

Groups of three students will choose a topic related to computer vision, and prepare a short survey on it.
Surveys should be based on about 12 papers (report: 5 pages max.).
You will make a presentation on your survey in class. The presentation should be in parallel with your report.
Survey topics should be confirmed first. Very similar topics to others’ will not be allowed (priority: first come, first served).
Your chosen survey topic and a few lines explanation (indicating group members) should be sent to dibeklioglu@cs.bilkent.edu.tr by 27 September 2024, 23.59 (Turkey time).

Project:

By groups of three students.
Projects related to your research topics are encouraged.
Build a “real” computer vision application and test it on some data.
You may re-use existing code, but indicate what you code you have re-used and what code you have developed yourself.
Three stages:

Proposal: one-page description of the project topic and the planning (indicating group members) for the project should be sent to dibeklioglu@cs.bilkent.edu.tr by 29 September 2024 (23:59 Turkey time)
Progress report & presentation (report: 2 pages max.)
Final report & presentation (report: 4 pages max.)

Examples of projects:

Performing face verification for automatic passport control
Recognizing the identity or expression of faces
Recognizing gestures for communication via sign language
Recognizing or detecting objects in images (Pascal VOC / ImageNet)
Segmenting parts in medical images
Performing restoration of old, deteriorated photographs
Performing automatic morphing of images
Performing video stabilization using object tracking
Identifying the writer of a piece of handwriting

Template for the Reports:
All reports (including homework report) must be prepared using the IEEE double-column transactions article template (i.e. "bare_jrnl.tex").
