In this post, I describe an animal recognition demonstration app I developed for the iPhone. The “MegaDetector-Demo” app uses the latest “MegaDetector” animal detector model from PyTorch-Wildlife to identify animals, people and vehicles in a live video feed from the iPhone camera. The demo app is available as an Xcode project for Apple developers on my GitHub site. I hope this basic app will encourage more practical uses of edge-based AI tech in trail cameras.
