The cata-fisheye camera is a panoramic imaging system which uses a curved mirror as a simple optical attachment to a fisheye lens. The cata-fisheye camera has a simple, compact and inexpensive design, and at the same time yields high optical performance.

The goal of this work is to create speech-enabled avatars of faces that provide realistic facial motion from text or speech inputs. Such speech-enabled avatars can significantly enhance user experience in a variety of applications including mobile messaging, information kiosks, advertising, news reporting and videoconferencing.

The field of view of a traditional camera has a fixed shape, which limits how we compose scene elements into an image. We present a novel imaging system with a flexible field of view - the size and shape of the field of view can be varied to achieve the desired scene composition
http://www1.cs.colum bia.edu/CAVE/project s/separation/
The goal of this project is to develop efficient methods for separating the direct and global (or indirect) components of a scene lit by a single light source and viewed by a camera. We show that the direct and global components at all scene points can be efficiently measured by using high frequency illumination patterns.
We develop a method based on projected and acquired lightfields, to have real and synthetic objects interact, including multiple bounces of global illumination between them.
