Degeneracies, dependencies and their implications in multi-body and multi-sequence factorizations

L Zelnik-Manor, M Irani - 2003 IEEE Computer Society …, 2003‏ - ieeexplore.ieee.org
The body of work on multi-body factorization separates between objects whose motions are
independent. In this work we show that in many cases objects moving with different 3D …

Articulated structure from motion by factorization

P Tresadern, I Reid - … Vision and Pattern Recognition (CVPR'05 …, 2005‏ - ieeexplore.ieee.org
Multibody affine structure from motion (SFM) methods commonly assume independent
motion between objects such that the'measurement matrix'has rank 4k. When multiple views …

Linear sequence-to-sequence alignment

F Padua, R Carceroni, G Santos… - IEEE Transactions on …, 2008‏ - ieeexplore.ieee.org
In this paper, we consider the problem of estimating the spatiotemporal alignment between
N unsynchronized video sequences of the same dynamic 3D scene, captured from distinct …

Photo sequencing

T Basha, Y Moses, S Avidan - … ECCV 2012: 12th European Conference on …, 2012‏ - Springer
Dynamic events such as family gatherings, concerts or sports events are often captured by a
group of people. The set of still images obtained this way is rich in dynamic content but lacks …

[PDF][PDF] Video synchronization via space-time interest point distribution

J Yan, M Pollefeys - Advanced Concepts for Intelligent Vision …, 2004‏ - people.inf.ethz.ch
We propose a novel algorithm to synchronize video recording the same scene from different
viewpoints. Our method relies on correlating space-time interest point distribution in time …

Tri-focal tensor-based multiple video synchronization with subframe optimization

C Lei, YH Yang - IEEE Transactions on Image Processing, 2006‏ - ieeexplore.ieee.org
In this paper, we present a novel method for synchronizing multiple (more than two)
uncalibrated video sequences recording the same event by free-moving full-perspective …

Video synchronization using temporal signals from epipolar lines

D Pundik, Y Moses - Computer Vision–ECCV 2010: 11th European …, 2010‏ - Springer
Time synchronization of video sequences in a multi-camera system is necessary for
successfully analyzing the acquired visual information. Even if synchronization is …

[PDF][PDF] Synchronizing Image Sequences of Non-Rigid Objects.

PA Tresadern, I Reid - BMVC, 2003‏ - robots.ox.ac.uk
For stereopsis, images of a given scene must be captured at the same instant to ensure
temporal consistency. For sequences of images (ie video streams) this requires the …

Video synchronization from human motion using rank constraints

PA Tresadern, ID Reid - Computer Vision and Image Understanding, 2009‏ - Elsevier
This paper presents a method of synchronizing video sequences that exploits the non-
rigidity of sets of 3D point features (eg, anatomical joint locations) within the scene. The …

Video synchronization based on co-occurrence of appearance changes in video sequences

M Ushizaki, T Okatani, K Deguchi - … International Conference on …, 2006‏ - ieeexplore.ieee.org
This paper presents a method for synchronizing multiple cameras from only the images
captured by the cameras, assuming that they are not connected to an external clock signal …
