Democratising Camera Trap AI: An Open-Source Model for Detecting UK Mammals

arXiv:2606. 10940v1 Announce Type: cross Abstract: Camera traps have become a cornerstone of biodiversity monitoring, but the artificial intelligence that turns vast quantities of images into usable ecological data is often locked behind commercial platforms or trained on fauna that does not match that of the British Isles.

Democratising Camera Trap AI: An Open-Source Model for Detecting UK Mammals

Camera traps have become a cornerstone of biodiversity monitoring, but the artificial intelligence that turns vast quantities of images into usable ecological data is often locked behind commercial platforms or trained on fauna that does not match that of the British Isles. In an attempt to remove barriers and increase uptake, we release an open-source object detection model for 31 classes, 28 common UK mammal and bird species, plus utility classes for humans, calibration poles, and vehicles, drawn from a curated dataset of 48,165 labelled instances assembled from multiple sites over a decade of operational deployment through Conservation AI and its successor, Trap Tracker.

Can Edge-Deployable Vision-Language Models Identify Species?

arXiv:2609. 11916v1 Announce Type: new Abstract: Camera traps often run in the field on edge hardware with limited or no connectivity, making small, locally-deployable vision-language models (VLMs) -- not frontier-scale ones -- the practically relevant class to evaluate for species identification.

PairCLIP-SWA: Similarity-Guided Balancing and Stochastic Weight Averaging for Generalized Deepfake Image Detection with OpenCLIP

PairCLIP‑SWA is a single‑backbone deepfake detector that fine‑tunes an OpenCLIP ViT‑L/14 visual tower using a class‑balanced corpus created by CLIP‑similarity‑guided subsampling and then applies stochastic weight averaging over the fine‑tuning trajectory. Trained on the IEEE SP Cup 2025 (DF‑Wild‑Cup) benchmark, the weight‑averaged model achieves 97.04 % accuracy, 98.64 % AU‑ROC and a 4.07 % equal error rate—outperforming the best published three‑backbone ensemble. The study shows that averaging stabilizes validation performance, prevents misranking on disjoint test sets, and that CLIP pre‑training, rather than ensembling, is the key driver of accuracy.

How well are open sourced AI-generated image detection models out-of-the-box: A comprehensive benchmark study

The study evaluates 16 AI‑generated image detection methods in a zero‑shot setting, testing 23 pretrained variants on 12 datasets with 2.6 million images from 291 generators. Results show no single detector consistently outperforms others, with accuracy ranging from 37.5 % to 75.0 %. The study highlights that training data alignment and generator type significantly affect performance, especially against modern commercial models, and identifies systematic failure patterns across datasets.

Three LiDARs, Twenty-Five Datasets: Cross-Source Generalization in Tree-Species Recognition

FOR-species20K is the largest public LiDAR benchmark for tree‑species classification, combining 25 datasets across 33 species. A multi‑resolution, multi‑view ConvNeXtV2 model raised the hidden‑test accuracy from 79.5 % to 85.0 %, placing first at submission. However, cross‑source experiments show that this score does not reflect true source‑disjoint generalization, with performance dropping dramatically when species are held out by source.

Multi-Scale ViT Inference with Habitat-Fit Priors and kNN Retrieval for Multi-Species Plant Identification

arXiv:2607. 14509v1 Announce Type: cross Abstract: This paper describes DS@GT ARC's third-place solution to the PlantCLEF 2026 challenge on multi-species plant identification in vegetation quadrat images, where systems must predict every species present in high-resolution (~3000 x 3000 pixel) plot photographs while training only on single-label images of individual plants.

WoodBR-Cross: A public wood-image dataset and individual-tree-disjoint benchmark for species identification

WoodBR-Cross is a new public dataset of 4,875 wood surface images grouped into 38 taxonomic classes and linked to 303 distinct trees, with a species-level subset of 3,406 images across 20 classes and 214 trees. The benchmark introduces three tasks that compare duplicate-aware image partitions, species subset partitions, and individual-tree-disjoint partitions, ensuring no tree appears in both training and test sets within a fold. Experiments with ResNet‑50, ConvNeXt‑Tiny, and ViT‑B/16 show that ConvNeXt‑Tiny and frozen DINOv2 features achieve macro‑F1 scores of 0.8621 and 0.9000, respectively, on the tree‑level disjoint split, providing realistic estimates of performance on unseen trees.
