DATAP-SfM: Dynamic-Aware Tracking Any Point for Robust Structure from Motion in the Wild

CoRR
This paper proposes a concise, elegant, and robust pipeline to estimate smooth camera trajectories and obtain dense point clouds for casual videos in the wild. Traditional frameworks, such as ParticleSfM~\cite{zhao2022particlesfm}, address this problem by sequentially computing the optical flow between adjacent frames to obtain point trajectories. They

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, Volume 2026, Issue 6, June 2026.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

The Flavonoids Daidzein and Genistein Induce Wall‐Deficient Cell Formation in Streptomyces coelicolor Under Hyperosmotic Stress

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Plant‐derived isoflavones (daidzein and genistein) function as chemical signals that induce stress‐dependent formation of wall‐deficient cells (S‐cells) in Streptomyces coelicolor. ABSTRACT Streptomycetes exhibit a complex multicellular life cycle, including programmed cell death and hyphal differentiation, and can generate extracellular vesicles and ...

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

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.

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, Volume 68, Issue 3, Page 298-310, June 2026.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Robust Bundle Adjustment for Structure from Motion

, 2006
Structure from motion (SFM) is the problem of reconstructing the geometry of a scene from a stream of images. In this problem, the geometry of the scene must be inferred from images, along with the camera pose parameters.

Refraction-Aware Structure from Motion for Airborne Bathymetry

Remote Sensing
In this work, we introduce the first pipeline that combines a refraction-aware structure from motion (SfM) method with a deep learning model specifically designed for airborne bathymetry. We accurately estimate the 3D positions of the submerged points by
