# Document OCR using Nanonets-OCR-s

This dataset contains markdown-formatted OCR results from images in [/content/my_dataset](https://huggingface.co/datasets//content/my_dataset) using Nanonets-OCR-s.

## Processing Details

- **Source Dataset**: [/content/my_dataset](https://huggingface.co/datasets//content/my_dataset)
- **Model**: [nanonets/Nanonets-OCR-s](https://huggingface.co/nanonets/Nanonets-OCR-s)
- **Number of Samples**: 1
- **Processing Time**: 4.6 minutes
- **Processing Date**: 2025-08-11 09:33 UTC

### Configuration

- **Image Column**: `image`
- **Output Column**: `markdown`
- **Dataset Split**: `train`
- **Batch Size**: 1
- **Max Model Length**: 8,192 tokens
- **Max Output Tokens**: 4,096
- **GPU Memory Utilization**: 80.0%

## Model Information

Nanonets-OCR-s is a state-of-the-art document OCR model that excels at:
- 📐 **LaTeX equations** - Mathematical formulas preserved in LaTeX format
- 📊 **Tables** - Extracted and formatted as HTML
- 📝 **Document structure** - Headers, lists, and formatting maintained
- 🖼️ **Images** - Captions and descriptions included in `<img>` tags
- ☑️ **Forms** - Checkboxes rendered as ☐/☑
- 🔖 **Watermarks** - Wrapped in `<watermark>` tags
- 📄 **Page numbers** - Wrapped in `<page_number>` tags

## Dataset Structure

The dataset contains all original columns plus:
- `markdown`: The extracted text in markdown format with preserved structure
- `inference_info`: JSON list tracking all OCR models applied to this dataset

## Usage

```python
from datasets import load_dataset
import json

# Load the dataset
dataset = load_dataset("{output_dataset_id}", split="train")

# Access the markdown text
for example in dataset:
    print(example["markdown"])
    break

# View all OCR models applied to this dataset
inference_info = json.loads(dataset[0]["inference_info"])
for info in inference_info:
    print(f"Column: {info['column_name']} - Model: {info['model_id']}")
```

## Reproduction

This dataset was generated using the [uv-scripts/ocr](https://huggingface.co/datasets/uv-scripts/ocr) Nanonets OCR script:

```bash
uv run https://huggingface.co/datasets/uv-scripts/ocr/raw/main/nanonets-ocr.py \
    /content/my_dataset \
    <output-dataset> \
    --image-column image \
    --batch-size 1 \
    --max-model-len 8192 \
    --max-tokens 4096 \
    --gpu-memory-utilization 0.8
```

## Performance

- **Processing Speed**: ~0.0 images/second
- **GPU Configuration**: vLLM with 80% GPU memory utilization
