Detector-Free Structure from Motion

, 2023
We propose a new structure-from-motion framework to recover accurate camera poses and point clouds from unordered images. Traditional SfM systems typically rely on the successful detection of repeatable keypoints across multiple views as the first step ...

Self-motion and the perception of stationary objects

, 2000
One of the ways we perceive shape is through seeing motion. Visual motion may be actively generated (for example, in locomotion), or passively observed.

Linear Structure From Motion

, 1994
Determining the structure of the world and the motion of the observer from image changes has been a central problem in computer vision for over fifteen years.

Structure from motion from three affine views

, 2002
We describe a new method for Structure From Motion from three affine views. The central idea of the method is to explore the intrinsic three-view properties instead of previous two-view ones.

Assessment of Structural Differences in a Low-Stature Mediterranean-Type Shrubland Using Structure-From-Motion (SfM)

Remote Sensing
Structural traits of vegetation, derived from the three-dimensional distribution of plant elements, are closely linked to ecosystem functions such as productivity and habitat provision. While extensively studied in forest ecosystems, these traits remain understudied in low-stature systems such as Mediterranean-type shrublands.

Unmanned aerial vehicle (UAV) remote sensing for hyperspatial terrain mapping of Antarctic moss beds based on structure from motion (SfM) point clouds

, 2011
This study is the first to use an Unmanned Aerial Vehicle (UAV) for mapping moss beds in Antarctica. Mosses can be used as indicators for the regional effects of climate change. Mapping and monitoring their extent and health is therefore important.

Rockfall hazard assessment using UAV photogrammetry and 3D modelling at Selmun Cliff in Malta

Discover Geoscience
Rockfalls represent a major hazard along the coastal cliffs of the Maltese Islands, where litho-structural settings dominated by Upper Coralline Limestone (UCL) overlying Blue Clay (BC) promote progressive slope instability.

Global Structure-from-Motion Revisited

Recovering 3D structure and camera motion from images has been a long-standing focus of computer vision research and is known as Structure-from-Motion (SfM). Solutions to this problem are categorized into incremental and global approaches. Until now, the

Body measurements of dairy cows using a structure from motion (SfM) photogrammetry approach

, 2017
The possibility of frequently monitoring calf body growth allows early recognition of health anomalies, and accordingly can reduce occurrence of problems connected to infertility or other diseases. In the last fifty years, manual measurement has been the
