# Dataset Card for Drone Maneuver Test-Clip Library

A benchmark of **41 six-second drone clips** (180 frames @ 30 fps)
cut from 20 KABR videos across 17 survey sessions at the Mpala Research Centre,
Kenya. Each clip is indexed by which autonomous-flight **maneuver** it can test
(launch / follow / behavior-adaptive / SoI-aware) and ships with a per-frame-per-track label table.
The library is intended for evaluating drone navigation policies against real wildlife footage.

## Dataset Details

### Dataset Description

- **Curated by:** Jenna Kline
- **Language(s) (NLP):** en
- **Homepage:** https://imageomics.github.io/wildlife-drone-maneuver/
- **Paper:** in prep
- **Related dataset:** [imageomics/KABR-mini-scene-raw-videos](https://huggingface.co/datasets/imageomics/KABR-mini-scene-raw-videos),
  [imageomics/KABR-raw-videos](https://huggingface.co/datasets/imageomics/KABR-raw-videos)

This dataset repackages the KABR aerial behavior dataset into short, mix-and-match clips that each
exercise a specific drone maneuver, so navigation policies can be benchmarked per-maneuver rather
than only end-to-end. Labels are aligned per frame per tracked individual.

### Supported Tasks and Leaderboards

Object detection / tracking, behaviour recognition, pose (viewpoint) estimation, and
**maneuver-conditioned navigation-policy evaluation** (the primary intended use).

```

The **source video** for each clip is referenced by its `fair2_video_eventID`, which resolves
in the [imageomics/kabr-full-release](https://huggingface.co/datasets/imageomics/kabr-full-release)
FAIR² dataset (`data/video_events.csv`); the session it belongs to is `fair2_session_eventID`
(`data/session_events.csv`). The catalog carries no absolute filesystem paths.

`clip_id = <date>-<video>_<start_frame>` (e.g. `18_01_2023_session_7-DJI_0070_000360`).

### Data Fields

**clips/<clip_id>/labels.csv** (one row per frame per track):
- `clip_id`, `video_id`, `session_id`: identifiers; `session_id` is the KABR/FAIR² session event.
- `frame_global`: absolute frame in the source video; `frame_local`: 0-based within the clip; `time_s`.
- `track_id`: KABR mini-scene id, **persistent within the source video**.
- `species`, `behavior`: KABR expert ground-truth labels; `vigilant`: behavior in {Head Up, Running, Trotting}.
- `pose`, `pose_provenance`, `pose_match_score`: 8-class viewpoint where ground-truth exists (see Annotations); else empty.
- `individual_id`: empty — global re-identification is future work (no ground truth exists).
- `xtl,ytl,xbr,ybr`, `x_c,y_c,w,h`, `bbox_area_frac`, `bbox_size_class` (far/medium/close, relative to this survey).
- `occluded`, `outside`: KABR annotation flags; `latitude`, `longitude`, `altitude`: drone telemetry; `date_time`.

**catalog/clip_index.csv** (one row per clip): identifiers, frame range, `species_set`, `habitat`,
`habitat_notes`, `habitat_provenance`, `herd_size`, `behaviours_present`, `has_vigilance`,
`bbox_size_classes`, `pose_set`, `suitable_maneuvers`, and the FAIR² event IDs
(`fair2_video_eventID` / `fair2_session_eventID`) that point back to the source video in
`imageomics/kabr-full-release`.

`habitat` is a structural class — **`open`**, **`closed`**, **`mixed`**, or **`unknown`** — so it can
be filtered and grouped consistently. It is derived from the original free-text field metadata
(Bitterlich relascope scores — a basal-area count, higher = denser woody canopy — plus field
remarks), which is preserved verbatim in **`habitat_notes`**. The binning is: Bitterlich 1–2 and
explicit "open" → `open`; Bitterlich 3–4, "mix", scattered/some bushes → `mixed`; Bitterlich ≥5
(e.g. 10) and "bushy" → `closed`; bare "near watering hole" / blank → `unknown`.

`habitat`/`habitat_notes` and `herd_size` are joined from the FAIR² `session_events`.
`habitat_provenance` records where each original habitat value came from: `session_event` (the
structured `habitat` field), `eventRemarks` (best-effort recovery from the free-text session remarks
where the structured field was blank), or empty (no habitat information available for that session).

**clips/<clip_id>/maneuver_labels.csv** (one row per frame per maneuver) — the **ground-truth drone
action** produced by replaying the formal maneuver decision tree over `labels.csv`:
- `maneuver`: one of `approach` / `track` / `behavior_adaptive` / `soi_aware`.
- `action_set_raw`, `action_set_smoothed`: the per-frame action(s) from the 9-action space
  (`up, down, forward, back, left, right, yaw-left, yaw-right, hover`); `smoothed` is the published
  label after a 3 s rolling average that suppresses jitter.
- `triggering_branch`: which decision-tree branch fired (for auditability).
- `S_t`, `pct_vigilant`, `centroid_x`, `centroid_y`, `mean_px`, `n_tracks`: the frame features the
  decision used, so any label is reproducible and inspectable.

### Evaluation harness (maneuver decision tree)

The accompanying replay harness (`clip_library/maneuver_labels.py`, spec in
`maneuver_decision_tree.md`) executes a small, inspectable **policy specification** deterministically
over each clip, emitting the action an expert-calibrated controller would take per frame. A learned
navigation policy can then be scored, per maneuver, against this reference. Every threshold
(vigilance `theta_S`, desired bbox pixels, SoI pose, smoothing window) is user-tunable; tuned runs
write a `maneuver_labels.custom.csv` sidecar and never overwrite the released labels. The harness is
CPU-only and runs on the released clips without the raw KABR archive.

## Dataset Creation

### Curation Rationale

Prior drone-ecology evaluation is end-to-end and offline. This library isolates the *maneuvers* an
autonomous drone must perform (approaching, following a herd, responding to disturbance, capturing a
desired viewpoint) into short replayable clips with aligned ground truth, so navigation policies can
be benchmarked per maneuver under realistic perception conditions.

### Source Data

KABR raw video release (Mpala Research Centre drone surveys, January 2023; DJI aircraft, 20–50 m altitude).
Clips are cut from the original videos; labels are joined from the KABR per-frame occurrence records.
See [KABR-mini-scene-raw-videos](https://huggingface.co/datasets/imageomics/KABR-mini-scene-raw-videos) and 
[KABR-raw-videos](https://huggingface.co/datasets/imageomics/KABR-raw-videos)

### Annotations — label provenance (read this)

Labels come from three distinct sources:

1. **Bounding box, species, behaviour — KABR expert ground truth.** Frame-by-frame CVAT annotations
   from the KABR project; carried over verbatim (duplicate merge-rows collapsed to one row per track per frame).
2. **Pose (8-class viewpoint) — ground-truth cross-reference, sparse.** Sourced from the manually
   labeled `imageomics/KABR-poses` crops (5 videos: DJI_0002, DJI_0006, DJI_0070, DJI_0145, DJI_0208).
   We deliberately do **not** run the DINOv2 pose classifier here: it was trained on these same KABR
   crops, so applying it would be inference on training data. Because a crop's filename identifies its
   frame but not its track, each labeled crop is matched to a KABR track by **visual disambiguation**
   among the candidate boxes at that frame; matches below a similarity threshold are flagged
   `pose_provenance = "gt-ambiguous"`. Of 227 crop assignments, 125 were flagged
   ambiguous (see `catalog/pose_audit.csv`). Pose coverage is sparse by design.
3. **Individual ID — absent (future work).** No global re-identification ground truth exists; only the
   within-video `track_id` is provided. Cross-video re-ID (e.g. MegaDescriptor) is left for future work.

#### Who are the annotators?

KABR project annotators (bounding boxes, behavior); the `imageomics/KABR-poses` curator (pose).
Maneuver-suitability tags are assigned programmatically by the selection pipeline.

### Personal and Sensitive Information

Wildlife only; no personal data. Species include Grevy's zebra (endangered) — coordinates are at
survey-session granularity.

## Considerations for Using the Data

### Bias, Risks, and Limitations

- **Pose is sparse** (5 videos) and best-effort track-matched; trust the `pose_provenance`/`pose_match_score` columns.
- **Species skew** toward Grevy's zebra; single site (Mpala); small bbox sizes throughout (20–50 m altitude),
  so "close/medium/far" are relative to this survey, not absolute scale.
- Labels are KABR ground truth, not model-generated — appropriate for ground-truth evaluation, not for
  characterizing perception error.
- Species/behaviour strings are normalized (`Walking`→`Walk`, `Grevy`→`Grevys Zebra`). The generic
  **`Zebra`** label is retained from KABR and means **undifferentiated zebra — Plains and/or Grevy's**:
  on those sessions the annotators did not split the two subspecies, so a `Zebra` clip may contain
  Plains zebra, Grevy's zebra, or both. This is a labeling-granularity difference, not noise; the
  explicit `Plains Zebra` / `Grevys Zebra` labels are used only where KABR distinguished them.
- Because GT pose is sparse, the **SoI-aware** maneuver labels are mostly `hover` (no-pose) on this
  release; the maneuver is fully exercised only with dense (model-generated) pose.

### Recommendations

Filter on `pose_provenance == "gt"` for confident pose; use `suitable_maneuvers` to select clips per
maneuver; cross-reference `session_id` to the KABR/FAIR² metadata for habitat and herd context.
