## Overview
| Property | Value |
|---|---|
| Total frames | **120,341** |
| Weed species | **16** |
| Growth duration | **11 weeks** |
| Total videos | **349** |
| Frame resolution | **720 x 960 pixels** |
| Annotation types | **Segmentation masks, Height (cm), Growth stage (week)** |
| Semantic classes | **17** (16 species + background) |
| Height range | **0.2 - 155 cm** |
## Data Splits
| Split | Images | Percentage |
|---|---|---|
| Train | 96,134 | ~80% |
| Validation | 12,333 | ~10% |
| Test | 11,874 | ~10% |
## Folder Structure
Large folders are distributed as **zip archives** (HF enforces a 10,000-file-per-directory limit).
```
train/
images.zip # RGB images (720 x 960) as .jpg
masks.zip # Segmentation masks (single-channel, class IDs 0-16) as .png
mmseg_masks.zip # Segmentation masks formatted for MMSegmentation as .png
xml.zip # VOC-format bounding box annotations as .xml
train_data.csv # Metadata: img, species, height, week
val/
images.zip
masks.zip
mmseg_masks.zip
xml.zip
val_data.csv
test/
images.zip
masks.zip
mmseg_masks.zip
xml.zip
test_data.csv
```
### After Extracting
Each zip extracts into a flat list of files. For example, `train/images.zip` contains:
```
ABUTH_week_10_IMG_1656_frame_0.jpg
ABUTH_week_10_IMG_1656_frame_1.jpg
SETFA_week_8_IMG_1344_frame_13.jpg
...
```
### File Naming Convention
All files follow the pattern: `{SPECIES}_week_{WEEK}_IMG_{VIDEO_ID}_frame_{FRAME}.{ext}`
Example: `SETFA_week_8_IMG_1344_frame_13.jpg`
### CSV Metadata
Each split CSV contains columns:
| Column | Type | Description |
|---|---|---|
| `img` | string | Image filename (e.g., `ABUTH_week_10_IMG_1656_frame_0.jpg`) |
| `species` | string | Weed species EPPO code (e.g., `ABUTH`, `SETFA`) |
| `height` | float | Plant height in centimeters (0.2 - 155.0 cm) |
| `week` | int | Growth stage week (1 - 11) |
### Segmentation Mask Values
| Pixel Value | Class |
|---|---|
| 0 | Background |
| 1 | ABUTH (Velvetleaf) |
| 2 | AMAPA (Palmer Amaranth) |
| 3 | AMARE (Redroot Pigweed) |
| 4 | AMATA / AMATU (Tall Waterhemp) |
| 5 | AMBEL (Common Ragweed) |
| 6 | CHEAL (Common Lambsquarters) |
| 7 | CYPES (Yellow Nutsedge) |
| 8 | DIGSA (Large Crabgrass) |
| 9 | ECHCG (Barnyardgrass) |
| 10 | ERICA (Horseweed) |
| 11 | PANDI (Fall Panicum) |
| 12 | SETFA (Giant Foxtail) |
| 13 | SETPU (Yellow Foxtail) |
| 14 | SIDSP (Prickly Sida) |
| 15 | SORHA (Johnsongrass) |
| 16 | SORVU (Shattercane) |
