|CS 410/510: Computational Photography|
|Instructor: Feng Liu|
|Office: Zoom (Appointment by email)|
|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.
Or its new version
Learning OpenCV 3: Computer Vision in C++ with the OpenCV Library
By Adrian Kaehler and Gary Bradski
These books provide not only a good reference to the OpenCV library, but also gives very good descriptions of a vast amount of vision algorithms.
*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.

|W1: 03/30||Class overview|
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.
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
firstname.lastname@example.org every Thursday afternoon before 4:00
In your email, please follow the following format for the email subject.
CS 410-510 Reading: You full name + Week number + Paper Title.
Your summary should be concise, no more than 500 words, and write in the plain text format in your email directly. 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
Giving a good technical talk is an important skill
for CS students. Every student needs to present one technical
paper in the class. The presentation should be around 30 minutes, including 3-5
minutes of Q & A.
Your presentation should include the following content.
Below is a list of advices on how to prepare and give a good technical talk.

You have the following three project options.
Option 2. System development
Option 3. Research
04/14: Submit a project proposal to email@example.com. In your email subject, put CS510 Project Proposal + Your name. If you work in group, only one member of the group needs to submit a copy and the proposal should list all the group members. Your summary need to be concise, less than 300 words.
