Decoding, Calibration and Rectification for Lenselet-Based Plenoptic Cameras
TL;DR: This work derives a novel physically based 4D intrinsic matrix relating each recorded pixel to its corresponding ray in 3D space as part of a decoding, calibration and rectification procedure for lenselet-based plenoptic cameras appropriate for a range of computer vision applications.
Journal ArticleDOI
Linear Volumetric Focus for Light Field Cameras
TL;DR: It is demonstrated that the redundant information in light field imagery allows volumetric focus, an improvement of signal quality that maintains focus over a controllable range of depths, and shows the hyperfan preserves depth of field, making it a single-step all-in-focus denoising filter suitable for general-purpose light field rendering.
Proceedings ArticleDOI
Plenoptic flow: Closed-form visual odometry for light field cameras
TL;DR: Three closed-form solutions are proposed for six degree of freedom (6-DOF) visual odometry for light field cameras, which avoid feature extraction and operate in constant time regardless of scene complexity, making them suitable for real-time robotics applications.
Proceedings ArticleDOI
Light field image denoising using a linear 4D frequency-hyperfan all-in-focus filter
TL;DR: The hyperfan preserves depth of field, making it a single-step all-in-focus denoising filter suitable for general-purpose light field rendering, and it is shown that the hyperfan’s performance scales with aperture count.
Proceedings ArticleDOI
Gradient-based depth estimation from 4D light fields
TL;DR: It is shown that an infinitesimally small surface element of a Lambertian scene exists as a plane of constant value in a 4D light field, where the orientation of the plane is determined by the depth of the element in the scene.
