CoastalWQL: An Open-Source Tool for Drone-Based Mapping of Coastal Turbidity Using Push Broom Hyperspectral Imagery

Remote Sensing
Uncrewed-Aerial Vehicles (UAVs) and hyperspectral sensors are emerging as effective alternatives for monitoring water quality on-demand. However, image mosaicking for largely featureless coastal water surfaces or open seas has shown to be challenging ...

Soybean variety development using aerial imagery and machine learning enabled phenomic‐assisted selection

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Traditional yield trials (YTs) are resource‐intensive and often limit genetic gain. This study assesses uncrewed aerial vehicle (UAV)‐based multispectral sensing for high‐throughput seed yield prediction for phenomic‐assisted selection (PAS) in a soybean [Glycine max (L.) Merr.] cultivar development program.

A computational framework for ultrastructural mapping of neural circuitry. [PDF]

PLoS Biology, 2009
Circuitry mapping of metazoan neural systems is difficult because canonical neural regions (regions containing one or more copies of all components) are large, regional borders are uncertain, neuronal diversity is high, and potential network topologies ...

Adaptive Habitat Selection Strategies of Human‐Breeding Red‐Crowned Cranes During the Early Stage of Rewilding

Ecology and Evolution, Volume 16, Issue 7, July 2026.
As an endangered species and cultural symbol in China, understanding the habitat preference of rewilded red‐crowned cranes is vital for their conservation strategies. By using 36,000 GPS points, we quantified habitat preference of rewilded red‐crowned cranes in Yancheng wetlands through a quantitative spatiotemporal PCA framework.

Evaluation strategy for image acquisition protocols in confocal microscopy mosaic imaging of the cornea

Current Directions in Biomedical Engineering
In vivo confocal laser-scanning microscopy (CLSM) of the cornea provides image data from the corneal tissues with cellular resoultion. The ability to resolve the nerve fiber bundles of the sub-basal nerve plexus (SNP), in particular, opens the ...

Hotspot magmatism and volcanic hazard at Cape Verde through the lens of shipborne surveying and dredging

Geology Today, Volume 42, Issue 4, Page 174-182, July/August 2026.
The Cape Verde archipelago is a long‐lived volcanic ocean island chain formed by a mantle plume in the Atlantic Ocean. The archipelago is characterized by ten subaerial islands with complex age relationships, abundant submarine volcanism and variable volcanic hazards.

An Improved Seeded Region Growing-Based Seamline Network Generation Method

Remote Sensing, 2018
To generate an orthoimage product, mosaicking is a necessary process, and seam-based mosaicking of orthoimages is popular. However, many of these methods only focus on the generation of seamlines between two adjacent orthoimages, so the final generated ...

Improving forest age estimation to understand subtropical forest regrowth dynamics using deep learning image segmentation of time‐series historical aerial photographs

Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 349-367, June 2026.
Accurately estimating forest age is key to understanding how forests recover and evaluating restoration success. We developed a two‐step deep learning approach using historical greyscale aerial photographs to map forest age at fine spatial scales. By combining a pre‐trained model with localized fine‐tuning, our U‐Net + ResNet50 architecture achieved ...

Flood Hazard Mapping in a Data‐Scarce Urban Watershed Using Analytical Hierarchy Process and Fuzzy Logic: A Case Study of Cuttack, India

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Floods are among the most frequent and damaging natural hazards in India, particularly affecting low‐lying urban areas in the eastern regions such as Cuttack, Odisha. This study aims to develop a flood hazard susceptibility map for the Cuttack district in Odisha, India, using a combined Analytical Hierarchy Process (AHP) and fuzzy logic ...
