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 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.

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.

Flexible Mirror Imagiing Flexible Mirror Imagiing

Video duration: 193 seconds

http://www1.cs.colum bia.edu/CAVE/project s/flexible_mirror/ 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
