WildDepth-v2: A Synchronized RGB--LiDAR--Radar Dataset and Benchmark for Metric Depth, Motion, and Tracking of Wildlife
Muhammad Aamir, Sangyun Shin, Naoya Muramatsu +4
Measuring animal distance and motion in metric units underpins abundance estimation, morphometrics, and movement ecology, yet monocular video lacks metric scale and wildlife datase…
A non-invasive video-based method for individual identification of wildlife using gait dynamics
Muhammad Aamir, Matthew Wijers, Sangyun Shin +2
Gait is a distinctive behavioral characteristic that enables non-invasive individual identification without requiring physical interaction with an animal. While gait-based analysis…
Spotted: Location-informed Reidentification of Hyenas and Leopards in Camera Trap Surveys
Halil Sina Kelebek, Julia Hindel, Kobus Hoffman +9
Animal re-identification (ReID) in camera-trap surveys remains challenging due to low image quality, strong variation in illumination and viewpoint, and highly imbalanced numbers o…
WildDepth: A Multimodal Dataset for 3D Wildlife Perception and Depth Estimation
Muhammad Aamir, Naoya Muramatsu, Sangyun Shin +6
Depth estimation and 3D reconstruction have been extensively studied as core topics in computer vision. Starting from rigid objects with relatively simple geometric shapes, such as…
AdS3 axion wormholes as stable contributions to the Euclidean gravitational path integral
Andrew Loveridge, Hao-Yu Sun
Recent work has demonstrated that Euclidean Giddings-Strominger axion wormholes are stable in asymptotically flat 4D Minkowski spacetime, suggesting that they should, at least naiv…
