  • A fanned hand of cards with detection boxes over each card's corner index

    Guandan Planner

    2026

    Mobile app that reads a full 27-card Guandan hand through the camera, entirely on-device, and arranges it into playable groups. Three subsystems built solo: a synthetic-data studio that renders the training set, a 3 MB corner detector with multi-frame evidence tracking, and a pure-Dart exact-cover arrangement engine. Flutter, iOS and Android.
