Long Short Term Memory Networks for Light Field View Synthesis

Because light field devices have a limited angular resolution, artificially reconstructing intermediate views is an interesting task. In this work, we propose a novel way to solve this problem using deep learning. In particular, the use of Long Short Term Memory Networks on a plane sweep volume is proposed. The approach has the advantage of having very few parameters and can be run on sequences with arbitrary length. We show that our approach yields results that are competitive with the state-of-the-art for dense light fields. Experimental results also show promising results with light fields with wider baselines.
