P3-15: Perceived 3D Shape from Motion for Small and Large Perspective Changes

i-Perception, 2012
Studies of structure-from-motion have generally found that perceived depth from motion is not veridical and depends on speed. However, some recent studies have found that metric shape perception can be yielded by large perspective changes (Bingham and ...

Data Fusion of Objects Using Techniques Such as Laser Scanning, Structured Light and Photogrammetry for Cultural Heritage Applications

, 2015
In this paper we present a semi-automatic 2D-3D local registration pipeline capable of coloring 3D models obtained from 3D scanners by using uncalibrated images.

Retrieving Mangrove Biophysical Properties using Drone-Based Structure-from-Motion (SfM) Photogrammetry

, 2021
Determination of biophysical properties of mangroves, e.g. tree height and diameter at breast height, is necessary for assessing mangrove ecosystem dynamics and growth.

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

ContextDesc: Local Descriptor Augmentation with Cross-Modality Context

, 2019
Most existing studies on learning local features focus on the patch-based descriptions of individual keypoints, whereas neglecting the spatial relations established from their keypoint locations.

On computing local monodromy and the numerical local irreducible decomposition

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

Comparative Functionality and Processing of Plant‐Proteins: A Path Toward Optimized Sustainable Plant‐Based Meat Analogues (PBMAs): A Review

Sustainable Food Proteins, Volume 4, Issue 2, June 2026.
The review provides a comprehensive comparison in terms comparison of commercially established and emerging plant protein sources, focusing on their structural, rheological, and sensory attributes for developing sustainable plant‐based meat analogues (PBMAs).

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.

The fascinating history of papillary thyroid carcinoma nuclei: revelation of two nuclear morphologies—“Classical papillary” and “papillary‐like”, with different pathobiologic characteristics

Cancer Cytopathology, Volume 134, Issue 5, May 2026.
Abstract The nucleus of papillary thyroid carcinoma (PTC) has had a fascinating history since its early descriptions by Lindsay in 1960 and his designation of follicular variant papillary thyroid carcinoma (FVPTC) as a subtype of follicular carcinoma (FC). Later, Chen and Rosai revived the awareness of FVPTC and aligned this neoplasm with PTC.

A closed-form solution to estimate uncertainty in non-rigid structure from motion

, 2020
Semi-Definite Programming (SDP) with low-rank prior has been widely applied in Non-Rigid Structure from Motion (NRSfM). Based on a low-rank constraint, it avoids the inherent ambiguity of basis number selection in conventional base-shape or base ...
