COMPREHENSIVE SPATIAL-GEOMETRIC EVALUATION OF KEYPOINT DETECTORS

Електроніка та інформаційні технології
Background. Local features are essential components of modern computer vision systems, such as SLAM and 3D reconstruction. Traditional evaluation protocols for keypoint detection mainly focus on geometric accuracy and repeatability, often neglecting the ...

Keypoint Promptable Re-Identification

Occluded Person Re-Identification (ReID) is a metric learning task that involves matching occluded individuals based on their appearance. While many studies have tackled occlusions caused by objects, multi-person occlusions remain less explored. In this work, we identify and address a critical challenge overlooked by previous occluded ReID methods: the

High‐Carbohydrate Diet Enhances Peripheral Nerve Regeneration via Hemoglobin Upregulation in Schwann Cells

Food Frontiers, Volume 7, Issue 4, July 2026.
A short‐term high‐carbohydrate diet enhances peripheral nerve regeneration more effectively than high‐protein or high‐fat diets by upregulating hemoglobin genes in Schwann cells. Increased hemoglobin promotes Schwann cell proliferation and migration, facilitating nerve repair.

River Ice Analyses and Roughness Calculations Using Underwater Drones and Photogrammetric Approach

Hydrological Processes, Volume 40, Issue 7, July 2026.
This study presents a methodology for determining hydraulic roughness (Manning's n) of fluvial ice using underwater drone and Structure from Motion (SfM) photogrammetry. The findings show that cost‐efficient equipment can be used to determine Manning's n for river ice, which supports modelling efforts, especially under intense warming in northern areas.
