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...

Rate-distortion optimized streaming of compressed light fields
We propose a framework for the streaming of light fields over a lossy error-prone packet network. This system is optimized for the end-user according to a rate-distortion criterio...

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...

Rate-distortion analysis of random access for compressed light fields
Image-based rendering data sets, such as light fields, require efficient compression due to their large data size, but also easy random access when rendering from the data set. Ef...

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...
