|   | Flexible Mirror Imaging,     ICCV Workshop on Omnidirectional Vision: OMNIVIS 2007 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.

|   | Multiview Radial Catadioptric Imaging for Scene Capture,     SIGGRAPH 2006 A picture taken by a conventional camera captures the scene from the camera's single viewpoint. In many applications in computer vision and computer graphics, it is desirable to capture the scene from a large number of viewpoints. In this project, we explore a class of imaging systems, called radial imaging systems, that capture a scene from circular loci of virtual viewpoints, in addition to the viewpoint of the camera. We have built radial imaging systems that can, from a single image, recover the frontal 3D structure of an object, generate the complete texture map of a convex object, and estimate the parameters of an analytic BRDF for an isotropic material. In addition, one of our systems can recover the complete geometry of a convex object by capturing only two images. [ PDF ]     [ Project Page ]     [ Slides ]     [ Slides w/ Videos]     |
