Abstract

Ventral metamers, pairs of images which may differ substantially in the periphery, but are perceptually identical, offer exciting new possibilities in foveated rendering and image compression, as well as offering insights into the human visual system. However, existing lit-erature has mainly focused on creating metamers of static images. In this work, we develop a method for creating sequences of metameric frames, specifically light fields, with enforced consistency along the temporal, or angular, dimension. This greatly expands the potential applications for these metamers, and expanding metamers along the third dimension offers further new potential for compression.
