## About

**TACO** is a computer-vision dataset curated and annotated on [Pictograph](https://pictograph.io/datasets/pictograph-research/taco). The most common detected objects are grass, sidewalk, bush, bottle, frisbee, ruins. On Pictograph you can browse every annotated image, fork it into your own workspace in one click, export it in a dozen formats, or train a model on it directly.

## At a glance

| Metric | Value |
| :--- | ---: |
| Images | 1,500 |
| Annotations | 4,784 |
| Classes | 60 |
| Annotation types | bounding box, polygon |
| Splits | train |

## Quick start

Load it in one line with the `datasets` library, then read each record's boxes and class names:

```python
from datasets import load_dataset
from PIL import ImageDraw

ds = load_dataset("pictograph/taco", split="train")
example = ds[0]
image = example["image"]            # a PIL image
objects = example["objects"]        # {bbox, categories, category_names}

# draw every bounding box with its class name
draw = ImageDraw.Draw(image)
for (x, y, w, h), name in zip(objects["bbox"], objects["category_names"]):
    draw.rectangle([x, y, x + w, y + h], outline="red", width=3)
    draw.text((x, y - 12), name, fill="red")

# polygon masks live under example["segmentation"]:
#   [{"label": name, "category": idx, "points": [[x, y], ...]}, ...]
image.show()
```

Prefer a full annotation editor, one-click fork, multi-format export, and one-click training? [Open this dataset on Pictograph](https://pictograph.io/datasets/pictograph-research/taco).

## Dataset structure

This dataset uses the Hugging Face `imagefolder` layout: each split directory holds the images plus a `metadata.jsonl` that links every image to its annotations by `file_name`.

| Field | Description |
| :--- | :--- |
| `file_name` | Path to the image within the split directory. |
| `objects.bbox` | Bounding boxes as `[x, y, width, height]` (pixels). |
| `objects.categories` | Integer class index per box (matches the class list below). |
| `objects.category_names` | Human class name per box. |
| `segmentation` | List of `{label, category, points}`; `points` is a polygon ring `[[x, y], ...]`. |

## Data instance

One record (bounding boxes are `[x, y, width, height]` in pixels; the class index maps into the class list below):

```python
{
  "image": <PIL.Image (RGB)>,
  "objects": {
    "bbox": [[172.0, 192.0, 249.4, 152.7]],
    "categories": [0],
    "category_names": ["Aerosol"]
  },
  "segmentation": [
    {"label": "Aerosol", "category": 0, "points": [[176.9, 207.2], [259.0, 274.1], ...]}
  ]
}
```

## Classes

Class index matches `objects.categories` in `metadata.jsonl`.
