Computational photography is a relatively new field at the convergence of photography, computer vision, image processing, and computer graphics. Its goal is to overcome the limitations of traditional photography using computational techniques to enhance the way we capture, manipulate, and interact with visual media. This course covers fundamentals and applications of hardware and software techniques, with an emphasis on software methods. We will study many interesting, recent image based algorithms and implement them to the degree that is possible.
We will cover topics such as
- Cameras and image formation
- Image stitching / completion / inpainting
- Texture synthesis, super-resolution, denoising.
- Light fields
- Image based lighting and rendering
- High dynamic range
- Intrinsic Images
- Coded aperture photography
- Modeling and synthesis using Internet data
- … more interesting topics.

Some of the materials used in class build on that from other instructors. In particular, we will use some materials from Gordon Wetzstein, Marc Levoy, Fredo Durand, Ramesh Raskar, Shree Nayar, and Alexei A. Efros, who in turn uses materials from Steve Seitz, Rick Szeliski, Paul Debevec, Stephen Palmer, Paul Heckbert, David Forsyth, Steve Marschner and others. Many thanks to them for sharing their work and knowledge.
