AI Insight

DeepForestVisionV2 is an improved artificial intelligence system for identifying wildlife from camera-trap images and videos in African tropical forests. The system expands from 35 to 64 species categories and was trained on over 1.5 million photographs and 243,000 videos from multiple African countries. Testing showed it achieves 86% accuracy on validation data and significantly improves identification of animals in diverse habitats including forest canopies, riverbanks, and areas with human activity, while reducing false alarms from 11 to 0 in challenging park-edge environments.


This tool enables more efficient and accurate automated wildlife monitoring across varied African forest habitats, reducing the labor-intensive manual review of millions of camera-trap images. The expansion to include arboreal primates, birds, semi-aquatic species, and human-related categories makes it practical for conservation monitoring in real-world settings where forests intersect with human activity.

Abstract: Camera-trap monitoring in African tropical forests increasingly extends beyond closed-canopy interiors to riverbanks, clearings, and park edges. Among available open tools for African forest camera-trap classification, DeepForestVision is the only one providing a matched offline workflow for both photographs and videos, and previous work showed that it outperformed other available baselines on a comparable benchmark. However, it was designed for closed-canopy, ground-level forest interiors and uses a 35-class prediction space that becomes too coarse when deployments encounter arboreal primates, birds, semi-aquatic taxa, or human-associated confounders such as livestock. We present DeepForestVisionV2, an ecology-driven expansion from 35 to 64 prediction classes (61 animal classes plus human, vehicle, and blank) designed to address three recurrent deployment gradients: vertical stratification, scene openness, and anthropogenic interfaces. DeepForestVisionV2 retains the same offline workflow and is trained on 1,535,010 photographs and 243,354 videos from multi-country African tropical-forest projects. Evaluation combines a cross-country cropped-photo validation set, used to assess robustness across sites and camera-trap settings, with three held-out Uganda video benchmarks spanning the targeted gradients. On the validation set, DeepForestVisionV2 reaches 0.86 accuracy, 0.82 macro-F1, and 0.81 balanced accuracy. On the deployment benchmarks, it preserves or improves baseline accuracy despite its harder classification task, while increasing the number of identified taxa from 22 to 29 in forest-interior videos and from 4 to 9 at riverbanks. In the park-edge use case, it raises accuracy from 0.62 to 0.86 and reduces false alarms from 11 to 0. These results show that DeepForestVisionV2 materially improves field utility while preserving robustness across sites, habitats, and camera-trap settings.
