High Fidelity Image-Based Modeling Google Tech Talks August 9, 2007 ABSTRACT In this talk, I will propose a novel algorithm for calibrated multi-view stereopsis that outputs a (quasi) dense set of rectangular patches covering the surfaces visible in the input images. This algorithm does not require any initialization in the form of a bounding volume, and it detects and discards automatically outliers and obstacles. It does not perform any smoothing across nearby features, yet is currently the top performer in terms of both coverage and accuracy for four of the six benchmarkdat asets presented in the Multi-View Stereo Evaluation (http://vision.middlebury.edu/mview/eval/). The keys to its performance are effective techniques for... Tags: google howto high fidelity image based |

Image-Based 3D Photography using Opacity Hulls We have built a system for acquiring and displaying high quality graphical models of objects that are impossible to scan with traditional scanners. Our system can acquire highly specular and fuzzy materials, such as fur and feathers. The hardware set-up consists of a turntable, two plasma displays, an array of cameras, and a rotating array of directional lights. We use multi-background matting techniques to acquire alpha mattes of the object from multiple viewpoints. The alpha mattes are used to construct an opacity hull. The opacity hull is a new shape representation, defined as the visual hull of the object with view-dependent opacity. It enables visualization of complex object silhouettes and seamless blending of objects into new environments. Our system also supports relighting of objects with arbitrary appearance using surface reflectance fields, a purely image-based appearance representation. Our system is the first to acquire and render surface reflectance fields under varying illumination from arbitrary viewpoints. We have built three generations of digitizers with increasing sophistication. In this paper, we present our results from digitizing hundreds of models. http://people.csail.mit.edu/wojciech/ Tags: 3D Photography scanning models opacity hull computer generated images CGI rendering image-based CG graphics scanner ibr |

Image-based visual hulls We describe an efficient image-based approach to computing and shading visual hulls from silhouette image data. Our algorithm takes advantage of epipolar geometry and incremental computation to achieve a constant rendering cost per rendered pixel. It does not suffer from the computation complexity, limited resolution, or quantization artifacts of previous volumetric approaches. We demonstrate the use of this algorithm in a real-time virtualized reality application running off a small number of video streams. http://people.csail.mit.edu/wojciech/ Tags: image based rendering ibr virtual reality 3d scanning video visual hull ibvh computer graphics cgi cg vr second life fx |

Augmented Reality with Image-based Lighting Realistic Illumination in Augmented Reality Application with Image-based Lighting. The Illumination of the surrounding is captured by a video camera from a mirrored sphere. Based on this image, two cubemap are calculated. One for diffuse illumination and one for specular illumination. The application is used for a AR-based Design Review of car models. Tags: Augmented Reality Image-based Lighting Design Review |

New Techniques for Acquiring, Rendering, and Displaying Human Performances Google Tech Talks February, 29 2008 ABSTRACT I will present recent work for acquiring, rendering, and displaying photoreal models of people, objects, and dynamic performances. I will overview image-based lighting techniques for photorealistic compositing and reflectance acquisition techniques which have been used to create realistic digital actors in films such as "Spider Man 2" and "Superman Returns". I will then describe initial work with our lab's Light Stage 6 system to combine image-based relighting with free-viewpoint video to capture and render full-body performances. I will also describe a new 3D face scanning process that captures high-resolution skin detail by estimating surface orientation from the skin's reflection of polarized spherical gradient illumination. I will conclude by describing a new 3D display that leverages 5,000 frames per second video projection to show autostereoscopic, interactive 3D imagery to any number of viewers simultaneously. Speaker: Dr. Paul Debevec, University of Southern California Institute for Creative Technologies Paul Debevec is the associate director of graphics research at USC's Institute for Creative Technologies (USC ICT) and a research associate professor at USC's Department of Computer Science. His Ph.D. thesis at UC Berkeley presented Façade, an image-based modeling and rendering system for creating photoreal virtual camera motion through architectural scenes from photographs. Using Façade he led the creation of a photoreal animation of the Berkeley campus for his 1997 film "The Campanile Movie" whose techniques were later used to create virtual backgrounds for the "The Matrix"; he went on to demonstrate new image-based lighting techniques in his animations "Rendering with Natural Light", "Fiat Lux", and "The Parthenon". He also led the design of HDR Shop, the first widely used high dynamic range image editing program. Paul received ACM SIGGRAPH's Significant New Researcher Award in 2001 and co-authored the book "High Dynamic Range Imaging" in 2005. Most recently, he chaired the SIGGRAPH 2007 Computer Animation Festival. Tags: google techtalks techtalk engedu talk talks googletechtalks education |
