Detecting TIPS Zones Zero-shot zone detection: text prompts → patch-grid cosine heatmaps → bboxes. Companion to — replaces manual / annotation with a TIPSv2 B/14 forward pass. Quick Start Amortise model load across multiple images: How It Works Why no softmax over labels Naïve softmax assumes labels are mutually exclusive. , , and are all true of the same pixels, so softmax collapses to near-uniform and every heatmap covers the whole subject. Raw cosines + per-label top-k threshold works much better — at the cost of requiring distractor labels to anchor the relative scale. Always pass some di…
