A focus measure for light field rendering
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 approximate...

Spatial domain analysis on the focus measurement for light field rendering
Light field rendering (LFR) is an image-based rendering method for synthesizing free-viewpoint images from a set of multi-view images. In LFR, no/little knowledge of geometry is r...

Unstructured light field rendering using on-the-fly focus measurement
This paper introduces a novel image-based rendering method which uses inputs from unstructured cameras and synthesizes free-viewpoint images of high quality. Our method uses a set...

All in-Focus View Synthesis from Under-Sampled Light Fields
Light field rendering (LFR) is a fundamental method for generating new views from a set of pre-acquired images. We use densely-aligned cameras for the process of acquiring the se...

A Theory of Aliasing Separation for Light Field Data
A light field means a 4-D function which characterizes the flow of light rays from a target scene, and used for image-based rendering. This paper presents a novel theoretical fr...
