All-Focused Light Field Rendering

by H. W. Jensen, A. Keller (editors, Akira Kubota, Keita Takahashi, Kiyoharu Aizawa, Tsuhan Chen , 2004
"... We present a novel reconstruction method that can synthesize an all in-focus view from under-sampled light fields, significantly suppressing aliasing artifacts. The presented method consists of two steps; 1) rendering multiple views at a given view point by performing light field rendering with di ..."

WATERMARKING FOR LIGHT FIELD RENDERING 1

by Alper Koz, Cevahir Çığla, A. Aydın Alatan
"... The recent advances in Image Based Rendering (IBR) have pioneered freely determining the viewing position and angle in a scene from multi-view video. Remembering that a person could also record a personal video for this arbitrarily selected view and misuse this content, it is apparent that copyright ..."

-interpolation based light-field rendering (LFR), is proposed. Watermark detection is achieved for the cases in which the virtual camera could be arbitrarily located on the camera plane only. This paper presents an extension to the previous formulation for the rendered images where the location of the virtual camera

Data Compression for Light Field Rendering

by Marcus Magnor, Bernd Girod, Fellow Ieee - IEEE Transactions on Circuits and Systems for Video Technology , 2000
"... Two light-field compression schemes are presented. The codecs are compared with regard to compression efficiency and rendering performance. The first proposed coder is based on video-compression techniques that have been modified to code the four-dimensional light-field data structure efficiently. T ..."

Towards Space-Time Light Field Rendering

by Huamin Wang, et al.
"... So far extending light field rendering to dynamic scenes has been trivially treated as the rendering of static light fields stacked in time. This type of approaches requires input video sequences in strict synchronization and allows only discrete exploration in the temporal domain determined by the ..."

Spherical light field rendering in application for analysis by synthesis

by S. Langer, M. Rezk-salama, K. -d - Intell. Systems Techn. and App., Issue on Dynamic 3D Imaging , 2008
"... Abstract: This paper presents a novel approach for object classifica-tion and pose estimation which employs spherical light field rendering to generate virtual views based on synthesis parameters determined and successively refined in a two-stage analysis by synthesis process. Com-pared to previous ..."

Light Field Rendering using Matrix Optics

by Lukas Ahrenberg, Marcus Magnor
"... This paper presents a light field rendering framework based on matrix optics. Matrix optics, in contrast to intersection-based methods such as ray-tracing, has the advantage that a generic series of optic operators can be combined into a single matrix. This enables us to realize a “virtual optical b ..."

A Focus Measure for Light Field Rendering

by Keita Takahashi, Akira Kubota, Takeshi Naemura - in proc. of ICIP’04 , 2004
"... Light field rendering is a fundamental method for synthesizing free-viewpoint images from a set of multi-viewpoint images. In the simplest case, the scene structure is approximated by a simple plane: a focal plane. This approximation leads to focus-like effects on synthetic images where the focused ..."

Efficient Free Form Light Field Rendering

by Hartmut Schirmacher, Christian Vogelgsang, Hans-peter Seidel, Günther Greiner , 2001
"... We show a simple and efficient way for rendering arbitrary views from so-called free-form light fields, employing a convex free form camera surface and a set of arbitrarily oriented camera planes. This way directionally varying real-world imagery can be displayed without intermediate resampling step ..."

A Geometric Analysis of Light Field Rendering
