| ## Scene Description |
|
|
| **Object type:** Human (complex scene) |
|
|
| **Goal:** Demonstrate that hyperspectral features beyond the visible spectrum improve person tracking in a crowded scene — fewer false ID switches and more reliable lock on the correct person than an RGB-only tracker can achieve. |
|
|
| **Setting:** Outdoor bus station with a busy pedestrian background. Camera on a static tripod roughly 100 m from the subject area, pointing at a section where pedestrians pass and wait. Hyperspectral data cube captured in video mode; spectral bands beyond the visible are exploited as tracking cues. |
|
|
| **Subjects:** Three actors — T (target), D1 (decoy 1), D2 (decoy 2). All three wear visually identical outfits so they look similar in the RGB projection of the hyperspectral cube. T wears a garment made of a material that looks distinct in CIR (colour infrared). This CIR difference is the spectral cue the tracker is expected to exploit. |
|
|
| **Passive phase:** Actors walk in single file toward or away from the camera, occluding one another along the optical axis. A visible-only tracker tends to swap IDs in this setting; hyperspectral cues should preserve the correct lock. |
|
|
| **Active phase:** While on camera, T carries a bottle of "invisible" ink that is visible only in specific spectral bands and sprays D1 with it. The spray adds a trackable spectral signature to D1 mid-recording. After marking, the three actors walk out of the scene from the opposite side, so the tail of the take shows the post-marking state. |
