# Molmo2-VideoTrackEval

Molmo2-VideoTrackEval is an evaluation benchmark for video point tracking, containing human-annotated ground truth expressions. It includes segmentation masks for evaluating whether predicted points fall within the correct object regions. Currently, there are five categories for evaluation:
- animal
- dance
- sports
- person
- misc

This benchmark is part of the [Molmo2 dataset collection](https://huggingface.co/collections/allenai/molmo2-data) and is used to evaluate the [Molmo2 family of models](https://huggingface.co/collections/allenai/molmo2) on video object tracking via point trajectories.

## Usage

```python
from datasets import load_dataset

# Load entire evaluation dataset
ds = load_dataset("allenai/Molmo2-VideoTrackEval", split="test")

# Load a specific benchmark subset by config name
animal = load_dataset("allenai/Molmo2-VideoTrackEval", "animal", split="test")
dance = load_dataset("allenai/Molmo2-VideoTrackEval", "dance", split="test")
sports = load_dataset("allenai/Molmo2-VideoTrackEval", "sports", split="test")
person = load_dataset("allenai/Molmo2-VideoTrackEval", "person", split="test")
misc = load_dataset("allenai/Molmo2-VideoTrackEval", "misc", split="test")
```

## Available Configs

| Config | Dataset | Description |
|--------|---------|-------------|
| `default` | All | All evaluation data combined |
| `animal` | APTv2 | Animal tracking benchmark |
| `dance` | dancetrack | Dancer tracking benchmark |
| `sports` | sportsmot | Sports player tracking benchmark |
| `person` | personpath22 | Person tracking benchmark |
| `misc` | sav | Misc Video benchmark |

## Data Format

Each row contains tracking annotations for one or more objects in a video clip:

| Field | Description |
|-------|-------------|
| `id` | Unique identifier for this annotation |
| `video` | Video filename |
| `clip` | trimmed clip id |
| `video_dataset` | Source dataset name (e.g., 'dancetrack', 'sportsmot') |
| `video_source` | Video directory path (can be ignored) |
| `exp` | Text expression describing the tracked object(s) |
| `obj_id` | List of object IDs per video |
| `mask_id` | List of mask IDs corresponding to tracked objects starting from '0' |
| `masks` | List of segmentation masks per object for evaluation. Each entry contains `object_id` and `masks` (used to verify if predicted points fall within the ground truth object region) |
| `points` | List of point trajectories per object. Each entry contains `object_id` and `points` (list of [x, y] coordinates per frame) |
| `segments` | List of segment annotations per object. Each entry contains `object_id` and `segments` |
| `start_frame` | Starting frame index for this clip |
| `end_frame` | Ending frame index for this clip |
| `w` | Video width |
| `h` | Video height |
| `n_frames` | Number of frames in the clip |
| `fps` | Frames per second |

**Important:** `start_frame` and `end_frame` indicate which portion of the source video to use. You need to trim the video to this range — the annotations correspond to frames within `[start_frame, end_frame]`, not the entire video.

### Evaluation with Masks

The `masks` field contains ground truth segmentation masks that can be used to evaluate tracking predictions. A predicted point is considered correct if it falls within the segmentation mask of the target object for that frame.
