Taxon-Specific Loss in Scleractinian Living Coral Area Following a Bleaching Event Is Linked to Reef Structural Decline in the Central Red Sea. [PDF]
Ecol EvolCoral bleaching is becoming more frequent and severe worldwide, yet its effects on reef structural complexity remain poorly understood compared with the well‐documented impacts on coral colonies and communities. We used a cross‐scale approach to link in situ thermal stress to coral colony‐scale bleaching and mortality and reef‐scale structural change ...

TC-SfM: Robust Track-Community-Based Structure-From-Motion
IEEE Transactions on Image ProcessingStructure-from-Motion (SfM) aims to recover 3D scene structures and camera poses based on the correspondences between input images, and thus the ambiguity caused by duplicate structures (i.e., different structures with strong visual resemblance) always results in incorrect camera poses and 3D structures.

Structure-from-Motion based vegetation modeling and shade estimation
, 2015 Although three-dimensional (3-D) light dimension and range (LiDAR) point cloud datasets describing the structure of vegetation have proven to be highly useful for ecological modeling, the collection of such data is expensive.

Incremental Structure from Motion for Small-Scale Scenes Based on Auxiliary Calibration
SensorsScarce feature points are a critical limitation affecting the accuracy and stability of incremental structure from motion (SfM) in small-scale scenes. In this paper, we propose an incremental SfM method for small-scale scenes, combined with an auxiliary ...

Open Geosciences, 2017 The article describes how the Structure-from-Motion (SfM) method can be used to calculate the volume of anthropogenic microtopography. In the proposed workflow, data is obtained using mass-market devices such as a compact camera (Canon G9) and a ...

Application of Photogrammetry and Mesh Comparison in the Study of Human Cranial Morphology
International Journal of Osteoarchaeology, EarlyView.ABSTRACT Photogrammetric methods for generating three‐dimensional (3D) models are becoming increasingly widespread in the fields of archaeology and biological anthropology. In particular, the study of the variability of skull morphology (generated by the ancestry of the individual or by the application of certain cultural practices) using 3D models is ...

Structure from motion (SFM) photogrammetry vs terrestrial laser scanning [PDF]
, 2016 Structure from Motion (SfM) has its roots in the well-established spatial measurement method of photogrammetry, but is becoming increasingly recognised as a means to capture dense 3D data to represent real-world objects, both natural and man- made.

Machine Learning Vegetation Filtering of Coastal Cliff and Bluff Point Clouds
Remote SensingCoastal cliffs erode in response to short- and long-term environmental changes, but predicting these changes continues to be a challenge. In addition to a chronic lack of data on the cliff face, vegetation presence and growth can bias our erosion ...

MP-SfM: Monocular Surface Priors for Robust Structure-From-Motion
2025 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)While Structure-from-Motion (SfM) has seen much progress over the years, state-of-the-art systems are prone to failure when facing extreme viewpoint changes in low-overlap, low-parallax or high-symmetry scenarios. Because capturing images that avoid these pitfalls is challenging, this severely limits the wider use of SfM, especially by non-expert users.

Human Prostate Cell Lines: Derivation, Molecular Characteristics and Appropriate Use
The Prostate, EarlyView.ABSTRACT Background Research on prostate cancer and benign prostatic hyperplasia depends on a small number of immortalized human cell lines established between 1977 and 2001, most of them from advanced metastatic disease. The cell lines differ from one another in androgen receptor status, prostate‐specific antigen secretion, p53 status, karyotype and ...
