We present a fully convolutional autoencoder for light fields, which jointly encodes stacks of horizontal and vertical epipolar plane images through a deep network of residual layers.

We introduce a novel approach to jointly estimate consistent depth and normal maps from 4D light fields, with two main contributions.
