The Frequency Structure Matrix: A Representation of Color Filter Arrays

This article introduces the frequency structure matrix as a new representation of color filter arrays (CFAs).

A Geometric Analysis of Light Field Rendering

In this paper,we adopt a geometric approach to investigate the minimum sampling problem for light field rendering, with and without geometry information of the scene.

Relighting with the Reflected Irradiance Field: Representation, Sampling and Reconstruction

We define a representation called the reflected irradiance field which records the light reflected from a scene as viewed at a fixed viewpoint as a result of moving a point light source on a plane.
