Query: Self-Supervised Deep Depth Denoising   Depth perception is considered an invaluable source of information for
various vision tasks. However, depth maps acquired using consumer-level sensors
still suffer from non-negligible noise. This fact has recently motivated
researchers to exploit traditional filters, as well as the deep learning
paradigm, in order to suppress the aforementioned non-uniform noise, while
preserving geometric details. Despite the effort, deep depth denoising is still
an open challenge mainly due to the lack of clean data that could be used as
ground truth. In this paper, we propose a fully convolutional deep autoencoder
that learns to denoise depth maps, surpassing the lack of ground truth data.
Specifically, the proposed autoencoder exploits multiple views of the same
scene from different points of view in order to learn to suppress noise in a
self-supervised end-to-end manner using depth and color information during
training, yet only depth during inference. To enforce selfsupervision, we
leverage a differentiable rendering technique to exploit photometric
supervision, which is further regularized using geometric and surface priors.
As the proposed approach relies on raw data acquisition, a large RGB-D corpus
is collected using Intel RealSense sensors. Complementary to a quantitative
evaluation, we demonstrate the effectiveness of the proposed self-supervised
denoising approach on established 3D reconstruction applications. Code is
