Query: Animatable Neural Radiance Fields from Monocular RGB-D   This paper aims at representing animatable photo-realistic humans under novel
views and poses. Recent work has shown significant progress with dynamic scenes
by exploring shared canonical neural radiance fields. However learning a
user-controlled model for novel poses remains a challenging task. To tackle
this problem, we introduce a novel method to integrate observations across
frames and encode the appearance at each individual frame by utilizing the
human pose that models the body shape and point clouds which cover partial part
of the human as the input. Specifically, our method simultaneously learns a
shared set of latent codes anchored to the human pose among frames, and learns
an appearance-dependent code anchored to incomplete point clouds generated by
monocular RGB-D at each frame. A human pose-based code models the shape of the
performer whereas a point cloud based code predicts details and reasons about
missing structures at the unseen poses. To further recover non-visible regions
in query frames, we utilize a temporal transformer to integrate features of
points in query frames and tracked body points from automatically-selected key
frames. Experiments on various sequences of humans in motion show that our
method significantly outperforms existing works under unseen poses and novel
views given monocular RGB-D videos as input.
