## Introduction

You know that RAG is very popular these days. There are many applications that support talking to documents. However,
there is a huge performance drop when talking to a complex document due to the complex structures. So it's a challenge
to extract content from complex document and organize it into parsable form. This repo aims to solve this challenge with
a fast and good performance method.

## Detection Sample

## Method

1. `YOLO` is the most advenced detect model developed by [Ultralytics](https://github.com/ultralytics/ultralytics). YOLO
   has 5 different sizes of base model and a super powerful framework for training and deployment. So I chose YOLO to
   solve this challenge.
2. `DocLayNet` is a human-annotated document layout segmentation dataset containing 80863 pages from a broad variety of
   document sources. As far as I know, it's the most qualified document layout analysis dataset.

## Usage

```python
from ultralytics import YOLO

model = YOLO("{path to model file}")
pred = model("{path to test image}")
print(pred)
```

## Dataset

DocLayNet can be found more details and download at this [link](https://github.com/DS4SD/DocLayNet). It has 11 labels:

- **Text**: Regular paragraphs.
- **Picture**: A graphic or photograph.
- **Caption**: Special text outside a picture or table that introduces this picture or
  table.
- **Section-header**: Any kind of heading in the text, except overall document title.
- **Footnote**: Typically small text at the bottom of a page, with a number or symbol
  that is referred to in the text above.
- **Formula**: Mathematical equation on its own line.
- **Table**: Material arranged in a grid alignment with rows and columns, often
  with separator lines.
- **List-item**: One element of a list, in a hanging shape, i.e., from the second line
  onwards the paragraph is indented more than the first line.
- **Page-header**: Repeating elements like page number at the top, outside of the
  normal text flow.
- **Page-footer**: Repeating elements like page number at the bottom, outside of the
  normal text flow.
- **Title**: Overall title of a document, (almost) exclusively on the first page and
  typically appearing in large font.
