DP-SfM: Dual-Pixel Structure-from-Motion without Scale Ambiguity

IEEE Transactions on Pattern Analysis and Machine Intelligence
Multi-view 3D reconstruction, namely, structure-from-motion followed by multi-view stereo, is a fundamental component of 3D computer vision. In general, multi-view 3D reconstruction suffers from an unknown scale ambiguity unless a reference object of known size is present in the scene.

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, Volume 95, Issue 11, Page 2277-2291, November 2026.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.

Flagella‐Mediated Biofilm Formation and 3D Swarming Drive Virulence in the Honey Bee Pathogen Paenibacillus larvae

Environmental Microbiology, Volume 28, Issue 11, November 2026.
The flagella of the bacterial pathogen Paenibacillus larvae, the etiological agent of American foulbrood in honey bees, were characterized and identified as virulence factors. These cellular appendages play key roles in biofilm formation and 3D swarming, two multicellular behaviours of P. larvae that contribute to pathogenesis.

Evaluation on the Accuracy of Structure From Motion（SfM）Photogrammetry on Gully Surveying

Shuitu baochi yanjiu, 2020
A typical gully was selected and measured using the tape method and structure from motion(SfM)photogrammetry in the village of Liangjianfang, Luanping County, Hebei Province. The accuracies of both gully surveying methods were evaluated via comparing the

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

Methods in Ecology and Evolution, Volume 17, Issue 11, Page 3136-3156, November 2026.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

Linear and Bilinear Subspace Methods for Structure from Motion

, 2001
Structure from Motion (SFM), which is recovering camera motion and scene structure from image sequences, has various applications, such as scene modeling, robot navigation and object recognition.

Flood Regime Structures Small Mammal Assemblages in Riparian Forests Along the Upper Paraguay River

Biotropica, Volume 58, Issue 6, November 2026.
Small‐mammal assemblages were sampled at 24 riparian‐forest sites across six landscapes along the Upper Paraguay River, spanning broad hydrological and vegetation gradients. Flood duration was more strongly associated with species composition than with species richness, while canopy height showed a negative association with observed richness ...

Mechanisms for seeing transparency-from-motion and orientation-from-motion

, 2000
Structure-from-motion (SFM) perception is hypothesised to be mediated by units that sense the near-far relationships in transparency-from-motion (TFM) and orientation-from-motion (OFM).

Learning Adaptive Filtering in the Fourier Domain for Fringe Pattern Analysis: A New Reconstruction Paradigm in Digital Holographic Interferometry

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
The object beam and the reference beam interfere at the camera sensor surface and multi‐angle tomographic recording based on off‐axis digital holography. ABSTRACT Single‐frame fringe pattern analysis in digital holographic interferometry (DHI) is essential for precision phase measurement under dynamic conditions. Recent advances in deep learning within
