Query: Deep Non-Line-of-Sight Reconstruction   The recent years have seen a surge of interest in methods for imaging beyond
the direct line of sight. The most prominent techniques rely on time-resolved
optical impulse responses, obtained by illuminating a diffuse wall with an
ultrashort light pulse and observing multi-bounce indirect reflections with an
ultrafast time-resolved imager. Reconstruction of geometry from such data,
however, is a complex non-linear inverse problem that comes with substantial
computational demands. In this paper, we employ convolutional feed-forward
networks for solving the reconstruction problem efficiently while maintaining
good reconstruction quality. Specifically, we devise a tailored autoencoder
architecture, trained end-to-end, that maps transient images directly to a
depth map representation. Training is done using an efficient transient
renderer for diffuse three-bounce indirect light transport that enables the
quick generation of large amounts of training data for the network. We examine
the performance of our method on a variety of synthetic and experimental
datasets and its dependency on the choice of training data and augmentation
strategies, as well as architectural features. We demonstrate that our
feed-forward network, even though it is trained solely on synthetic data,
generalizes to measured data from SPAD sensors and is able to obtain results
that are competitive with model-based reconstruction methods.
