Gabriel Takacs,Vijay Chandrasekhar,Natasha Gelfand,Yingen Xiong,Wei-Chao Chen,Thanos Bismpigiannis,Radek Grzeszczuk,Kari Pulli,Bernd Girod +8 more
TL;DR: An outdoors augmented reality system for mobile phones that matches camera-phone images against a large database of location-tagged images using a robust image retrieval algorithm and shows a smart-phone implementation that achieves a high image matching rate while operating in near real-time.

Multi-projector displays using camera-based registration
Ramesh Raskar,Michael S. Brown,Ruigang Yang,Wei-Chao Chen,Gregory F. Welch,Herman Towles,B. Scales,Henry Fuchs +7 more
TL;DR: Flexible yet practical methods are presented, enabling low-cost mega-pixel display systems with large physical dimensions, higher resolution, or both, and new opportunities to build personal 3D visualization systems in offices, conference rooms, theaters, or even your living room.
Proceedings ArticleDOI
Light field mapping: efficient representation and hardware rendering of surface light fields
TL;DR: A compact representation suitable for an accelerated graphics pipeline to enable the use of surface light fields in real-time rendering is developed and a new method of approximating the light field data is implemented that produces positive only factors allowing for faster rendering using simpler graphics hardware than earlier methods.
Proceedings ArticleDOI
Artifact-free High Dynamic Range imaging
TL;DR: This work presents a technique capable of dealing with a large amount of movement in the scene: it finds, in all the available exposures, patches consistent with a reference image previously selected from the stack and generates the HDR image by averaging the radiance estimates of all such regions.
