This paper addresses the problem of rigid-motion synchronization (aka motion averaging) in
the Special Euclidean Group SE (3), which finds application in structure-from-motion and …

This paper deals with the synchronization problem, which arises in multiple 3D point-set
registration and in structure-from-motion. The problem is formulated as a low-rank and …

In this paper we survey and put in a common framework several works that have been
developed in different contexts, all dealing with the same abstract problem, called …

This paper proposes a robust method to solve the absolute rotation estimation problem,
which arises in global registration of 3D point sets and in structure-from-motion. A novel cost …

Some 3D computer vision techniques such as structure from motion (SFM) and augmented
reality (AR) depend on a specific perspective-n-point (PnP) algorithm to estimate the …

This paper deals with the problem of estimating camera motion in the context of structure-
from-motion. We describe a pipeline that consumes relative orientations and produces …

The ability to identify anomalous traffic patterns is a central issue for network managers:
primarily lots of problems could arise from network attacks, such as viruses and tunneling …

This paper deals with the problem of recovering the unknown norm of relative translations
between cameras based on the knowledge of relative rotations and translation directions …

运动恢复结构(SFM) 是指通过分析二维图像序列恢复三维结构信息的过程, 在计算机视觉的多种
应用中起着重要的作用. 特征跟踪是大规模SFM 的核心组成部分, 但现有的多视图特征跟踪算法 …

相机位姿估计作为SFM 的关键环节, 其估计精度直接影响三维重建结果, 而在增量式SFM
的迭代过程中, 经常出现由于相机位姿估计误差累积而在最终重建结果中产生漂移问题 …
