# Block Diagram Global Information Extractor

It was introduced in the paper **"Unveiling the Power of Integration: Block Diagram Summarization through Local-Global Fusion"** accepted at ACL 2024. The full code is available in this [BlockNet](https://github.com/shreyanshu09/BlockNet) github repository.


## Model description

This model is trained using a transformer encoder and decoder architecture, based on the configuration specified in [Donut](https://arxiv.org/abs/2111.15664), to extract the overall summary of block diagram images. It supports both English and Korean languages. The straightforward architecture comprises a visual encoder module and a text decoder module, both based on the Transformer architecture.


## Training dataset
- 41,933 samples from the synthetic and real-world block diagrams in English language (BD-EnKo)
- 33,101 samples from the synthetic and real-world block diagrams in Korean language (BD-EnKo)
- 396 samples from real-world English block diagram dataset (CBD)
- 357 samples from handwritten English block diagram dataset (FC_A)
- 476 samples from handwritten English block diagram dataset (FC_B)

## How to use

Here is how to use this model in PyTorch:

```python
import os
from PIL import Image
import torch
from donut import DonutModel

# Load the pre-trained model
model = DonutModel.from_pretrained("shreyanshu09/block_diagram_global_information") 

# Move the model to GPU if available
if torch.cuda.is_available():
    model.half()
    device = torch.device("cuda:0")
    model.to(device)
    
# Function to process a single image
def process_image(image_path):
    # Load and process the image
    image = Image.open(image_path)
    task_name = os.path.basename('/block_diagram_global_information/dataset/c2t_data/')                  # Create empty folder anywhere
    result = model.inference(image=image, prompt=f"<s_{task_name}>")["predictions"][0]

    # Extract the relevant information from the result
    if 'c2t' in result:
        return result['c2t']
    else:
        return result['text_sequence']

# Example usage
image_path = 'image.png'                  # Input image file
result = process_image(image_path)
```
