  Monocular depth reconstruction of complex and dynamic scenes is a highly
challenging problem. While for rigid scenes learning-based methods have been
offering promising results even in unsupervised cases, there exists little to
no literature addressing the same for dynamic and deformable scenes. In this
work, we present an unsupervised monocular framework for dense depth estimation
of dynamic scenes, which jointly reconstructs rigid and non-rigid parts without
explicitly modelling the camera motion. Using dense correspondences, we derive
a training objective that aims to opportunistically preserve pairwise distances
between reconstructed 3D points. In this process, the dense depth map is
learned implicitly using the as-rigid-as-possible hypothesis. Our method
provides promising results, demonstrating its capability of reconstructing 3D
from challenging videos of non-rigid scenes. Furthermore, the proposed method
also provides unsupervised motion segmentation results as an auxiliary output.
