# LLM-Pack: Grocery Detection Dataset

A small object detection and scene understanding dataset containing tabletop grocery scenes with annotated item names and object locations.
The dataset consists of 40 images with varying object counts, designed for evaluating object detection, counting, and multimodal reasoning systems in cluttered grocery scenarios.

## Dataset Overview

- **Total scenes:** 40
- **Object counts per scene:** 6, 8, 10, 12, 14, 16, 18, or 20 items
- **Samples per object-count category:** 5
- **Annotations:** Object names + object center coordinates
- **Image resolution:** 1920×1080
- **Task type:** Object detection / scene understanding / counting

## Dataset Structure

Each sample contains:

```python
{
    "image": PIL.Image,
    "caption": str,
    "bucket": str, # number of items on the image
    "sample_id": str,

    "labels": List[str],
    "annotation_indices": List[int],
    "annotation_x": List[int],
    "annotation_y": List[int],

    "annotation_count": int
}
```

## Annotation Format

Object annotations are stored as aligned lists.

Example:

```python
{
    "labels": [
        "Glass Beer Bottle",
        "Apples",
        "Noodles in Plastic Bag"
    ],

    "annotation_x": [1480, 1251, 1123],
    "annotation_y": [445, 822, 810]
}
```

Each `(annotation_x[i], annotation_y[i])` pair corresponds to the center position of `labels[i]` in the image.

## Usage

```python
from datasets import load_dataset

dataset = load_dataset(
    "Yannik019/llm_pack_detection",
    split="train"
)

print(dataset)
```

## Example

A full usage example is available here:

## Intended Use

This dataset is intended for:

- Object detection benchmarking
- Vision-language model evaluation
- Scene understanding research
- Tabletop grocery perception
- Referring object localization
