Incremental Structure-from-Motion is a prevalent strategy for 3D reconstruction from unordered image collections.
We show that both hard-positive and hard-negative examples, selected by exploiting the geometry and the camera positions available from the 3D models, enhance the performance of particular-object retrieval.
Convolutional Neural Networks (CNNs) achieve state-of-the-art performance in many computer vision tasks.

We present an algorithm for reconstructing dense, geometrically consistent depth for all pixels in a monocular video.
We validate the use of large amounts of Internet data by showing that models trained on MegaDepth exhibit strong generalization-not only to novel scenes, but also to other diverse datasets including Make3D, KITTI, and DIW, even when no images from those datasets are seen during training.

In this paper we formulate structure from motion as a learning problem.

We propose a framework that extends Blender to exploit Structure from Motion (SfM) and Multi-View Stereo (MVS) techniques for image-based modeling tasks such as sculpting or camera and motion tracking.
We propose C3DPO, a method for extracting 3D models of deformable objects from 2D keypoint annotations in unconstrained images.
After local reconstructions, we construct a minimum spanning tree (MinST) to find accurate similarity transformations.
We propose DeepV2D, an end-to-end deep learning architecture for predicting depth from video.
