hae — find people in thermal drone imagery

Open person detectors for search-and-rescue drones, small enough for a $15 Raspberry Pi Zero 2 W: hae-s-ir (313 k parameters, 383 KB int8), the general model, and hae-n-ir-ext-kdf (54 k parameters, 123 KB int8), the real-time model for forest and wilderness footage. Here they run in your browser with ONNX Runtime Web: your image never leaves your device. Code and weights: MIT.

Decision support only. The model misses people and raises false alarms. Never use it as the only means of search.
