ResAF-Net: Anchor-Free AI for Tree Detection in Palestine

ai-technology · 2026-04-29

A new satellite-based tree detection framework, ResAF-Net, has been developed for large-scale agricultural monitoring in Palestine, where fragmented landscapes and restrictions on aerial monitoring hinder data collection. The architecture combines a ResNet-50 encoder, Atrous Spatial Pyramid Pooling, feature fusion, multi-head self-attention, and an anchor-free FCOS detection head. Trained on the MillionTrees benchmark, it achieved 82% Recall, 63.03% mAP@0.50, and 35.47% mAP@0.50:0.95 on validation, showing strong sensitivity to tree presence.
