Bayesian structure from motion
Proceedings of the Seventh IEEE International Conference on Computer Vision, 1999Formulates structure from motion as a Bayesian inference problem and uses a Markov-chain Monte Carlo sampler to sample the posterior on this problem. This results in a method that can identify both small and large tracker errors and yields reconstructions that are stable in the presence of these errors.

Semantic structure from motion
CVPR 2011, 2011Conventional rigid structure from motion (SFM) addresses the problem of recovering the camera parameters (motion) and the 3D locations (structure) of scene points, given observed 2D image feature points. In this paper, we propose a new formulation called Semantic Structure From Motion (SSFM).

Structure-from-Motion Revisited
2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2016Incremental Structure-from-Motion is a prevalent strategy for 3D reconstruction from unordered image collections. While incremental reconstruction systems have tremendously advanced in all regards, robustness, accuracy, completeness, and scalability remain the key problems towards building a truly general-purpose pipeline.

With increasing computational capacity, it is becoming easier to simulate much of the human brain activity. Similar to left and right eyes coordination to perceive shape and distance of the surrounding objects, we can use cameras to get the images of an object from different angles and perform a popular Computer Vision technique known as Structure from

Polynomial Methods For Structure From Motion
[1988 Proceedings] Second International Conference on Computer Vision, 1990The authors analyze the limitations of structure from motion (SFM) methods presented in the literature and propose the use of a polynomial system of equations, with the unit quaternions representing rotation, to recover SFM under perspective projection.

Recursive Structure from Motion
2017In this paper we present a technique that estimates the Structure from Motion (SFM) in a recursive fashion. Traditionally successful SFM algorithms take the set of images and estimate the scene geometry and camera positions either using incremental algorithms or the global algorithms and do the refinement process [2] to reduce the reprojection error ...

Structure From Motion on XSlit Cameras
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2021We present a structure-from-motion (SfM) framework based on a special type of multi-perspective camera called the cross-slit or XSlit camera. Traditional perspective camera based SfM suffers from the scale ambiguity which is inherent to the pinhole camera geometry. In contrast, an XSlit camera captures rays passing through two oblique lines in 3D space

Autocalibration for Structure from Motion
Computer Vision and Image Understanding, 2017Calibration pipeline that propagates calibration information to uncalibrated images.Estimated calibration includes focal length, distortion center and distortion parameter.Bigger datasets may be used and optimization step in SfM is more likely to converge without getting stuck in local minima.

Multibody Structure-from-Motion in Practice
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010Multibody structure from motion (SfM) is the extension of classical SfM to dynamic scenes with multiple rigidly moving objects. Recent research has unveiled some of the mathematical foundations of the problem, but a practical algorithm which can handle realistic sequences is still missing.

Resampling Structure from Motion
2010This paper proposes a hierarchical framework that resamples 3D reconstructed points to reduce computation cost on time and memory for very large-scale Structure from Motion. The goal is to maintain accuracy and stability similar for different resample rates.
