CS 510/610: Computational Photography
Instructor: Feng Liu
|Office: FAB 120-09|
|Office Hours: TR 15:30-16:30|
|Computational photography is a field where computer graphics, computer vision, optics, and photography come together to create high-quality pictures. This course will discuss computational techniques to overcome the limitations of traditional cameras and enhance their capabilities. This course will cover topics ranging from concepts of digital camera and photography to computer vision and graphics techniques for creating high-quality pictures, including high dynamic range imaging, panorama stitching, image segmentation & matting, video stabilization, etc.|
|General Course Information|
|We do not require any textbooks for this class. But the following two books will be very helpful.|
Computer Vision: Algorithms and Applications, by R. Szeliski
This book is available online. Please download its latest version.
Learning OpenCV: Computer Vision with the OpenCV Library,
by Gary Bradski and Adrian Kaehler.
This book provides not only a good reference to the OpenCV library, but also gives very good descriptions of a vast amount of vision algorithms.
Acknowledgement: Many of the lecture notes were modified from materials for similar classes taught at other universities by Professor Yung-Yu Chuang, Fr¨¦do Durand, Chuck Dyer, Marc Levoy, Steve Seitz, Li Zhang, and Dr. Stephen Chenney and Richard Szeliski. Without their generous help, this class could not have been developed.

You might need to be on the PSU network or have an ACM/IEEE
account to download some of papers.
# You cannot select readings from a book for your reading assignment.
Each week, you will read a few papers posted in the course web page. Besides, you need to pick one of the papers you read, write and send a short summary to email@example.com every Thursday afternoon before 500 pm.
In your email, please follow the following format for the email subject.
CS 510 Reading: You full name + Week number + Paper Title.
Your summary should be concise, no more than 500 words. You need to address the following five questions if appropriate.
1. What problem is addressed?
2. How it is solved?
3. The advantages of the presented method?
4. The limitations of the presented method?
5. Future work
You have the following three project options.
Option 2. System development
Option 3. Research
04/16: Submit a project proposal to firstname.lastname@example.org. In your email subject, put CS510 Project Proposal + Your name. If you work in group, each of the group member needs to submit a copy, which can be identical. Your summary need to be concise, less than 300 words.
06/03-06/05: In class project presentation.
06/12: Final submission. You need to submit a copy of your code with test data and project report. Please do not send the project package via email directly and send me a link instead. In your email subject, put CS510 Project + Your name. If you work in group, each of the group member needs to submit a copy, which can be identical. The deadline is 11:59 pm, 06/12.
Your project report shall follow the format of a technique paper that you read in this class.
If your project is of Option 2 or 3, your report shall include abstract, introduction, related work, method, experiment, and conclusion.
Do not copy the text from the paper that you implemented. Be clear in your report that you implemented other people's method instead of inventing the method by yourself.
