CAM-Convs: Camera-Aware Multi-Scale Convolutions for Single-View Depth
[article]
2019
arXiv
pre-print
Preserved Fulltext
Single-view depth estimation suffers from the problem that a network trained on images from one camera does not generalize to images taken with a different camera model. ...
In this work, we propose a new type of convolution that can take the camera parameters into account, thus allowing neural networks to learn calibration-aware patterns. ...

By taking an inverse problem view, we design a single convolutional neural network (CNN) that successfully estimates depth and 3D motion simultaneously from a classical optical flow cost volume. ...
Our model achieves state-of-the-art accuracy among unsupervised/self-supervised learning approaches to monocular scene flow, and yields competitive results for the optical flow and monocular depth estimation ...
Upon the augmentation, we also explore the recent CAM-Convs [9] , which facilitate depth estimation irrespective of the camera intrinsics. ...

In particular, the generation of new images at parallel camera views given a single input image is of great interest, as it enables 3D visualization of the 2D input scenery. ...
However, solving the single-image-based view synthesis is still an open problem. ...
It should be noted that the work of Facil et al. (2019) only handled the supervised monocular depth estimation task for multiple datasets with different camera intrinsics utilizing "CAM-Convs", which ...
