This paper presents a novel volumetric reconstruction technique that combines shape-from-silhouette with stereo photo-consistency in a global op-timisation that enforces feature constraints across multiple views. Human shape reconstruction is considered where extended regions of uniform appearance , complex self-occlusions and sparse feature cues represent(More)
We constructed a personal, spherical, multi-projector perspective-corrected rear-projected display called <i>Spheree.</i> Spheree uses multiple calibrated pico-projectors inside a spherical display with content rendered from a user-centric viewpoint. Spheree uses optical tracking for head-coupled rendering, providing parallax-based 3D depth cues. Spheree is(More)
This contribution introduces a new approach of using multi-camera images of an event to provide a free-viewpoint video visualisation of sport scenes. This allows a virtual camera to be moved freely around and to view the action from any angle. The system is based on 3D reconstruction techniques previously developed for studio use. A number of different 3D(More)
The visual hull is widely used to produce three dimensional models from multiple views, due to the reliability of the resulting surface. This paper presents a novel method for efficiently evaluating the exact view-dependent visual hull without using approximations. Methods for selecting intersections and ordering them via the cross ratio are presented.(More)
Recently there have been a number of proposals for the use of artificial evolution as a radically new approach to the development of control systems for autonomous robots. This paper explains the artificial evolution approach, using work at Sussex to illustrate it. The paper revolves around a case study on the concurrent evolution of control networks and(More)
In this paper we introduce a video-based representation for free viewpoint visualization and motion control of 3D character models created from multiple view video sequences of real people. Previous approaches to video-based rendering provide no control of scene dynamics to manipulate, retarget, and create new 3D content from captured scenes. Here we(More)
We have built a novel vision processing system architecture called Hive. Hive fills a gap in the vision middleware by providing mechanisms for simple setup and configuration of distributed vision computation. Hive facilitates communication between independent cross-platform modules via an extensible protocol, allowing these distributed modules to form a(More)
This paper introduces a representation for multiple view video to support high-quality interactive free-viewpoint rendering of moving people. Multiple wide baseline views are integrated into a view-dependent representation based on pair wise refinement of the visual-hull. An exact view-dependent visual-hull (VDVH) algorithm is presented to compute an(More)
Target selection is a fundamental aspect of interaction and is particularly challenging when targets are moving. We address this problem by introducing a novel selection technique we call Hold which temporarily pauses the content while selection is in progress to provide a static target. By studying users, we evaluate our method against two others for(More)
