HINT-3D: Human-In-The-Loop Interactive Test-Time Adaptation for 3D Segmentation

We present HINT-3D, a human-in-the-loop test-time adaptation framework for 3D semantic segmentation. A few corrective clicks are converted into region masks by a promptable 3D interface (PointSAM). These masks supervise stability-aware updates to a pre-trained backbone at inference. We persist the u…
