# TF-ID: Table/Figure IDentifier for academic papers

## Model Summary

TF-ID (Table/Figure IDentifier) is a family of object detection models finetuned to extract tables and figures in academic papers. They come in four versions:
| Model   | Model size | Model Description | 
| ------- | ------------- |   ------------- |  
| TF-ID-base[[HF]](https://huggingface.co/yifeihu/TF-ID-base) | 0.23B  | Extract tables/figures and their caption text  
| TF-ID-large[[HF]](https://huggingface.co/yifeihu/TF-ID-large) | 0.77B  | Extract tables/figures and their caption text  
| TF-ID-base-no-caption[[HF]](https://huggingface.co/yifeihu/TF-ID-base-no-caption) | 0.23B  | Extract tables/figures without caption text
| TF-ID-large-no-caption[[HF]](https://huggingface.co/yifeihu/TF-ID-large-no-caption) | 0.77B  | Extract tables/figures without caption text
All TF-ID models are finetuned from [microsoft/Florence-2](https://huggingface.co/microsoft/Florence-2-large-ft) checkpoints.

TF-ID models take an image of a single paper page as the input, and return bounding boxes for all tables and figures in the given page. 
TF-ID-base and TF-ID-large draw bounding boxes around tables/figures and their caption text.
TF-ID-base-no-caption and TF-ID-large-no-caption draw bounding boxes around tables/figures without their caption text.

Object Detection results format: 
{'\<OD>': {'bboxes': [[x1, y1, x2, y2], ...], 
'labels': ['label1', 'label2', ...]} }
 
## How to Get Started with the Model

Use the code below to get started with the model.

```python
import requests

from PIL import Image
from transformers import AutoProcessor, AutoModelForCausalLM 


model = AutoModelForCausalLM.from_pretrained("microsoft/Florence-2-base-ft", trust_remote_code=True)
processor = AutoProcessor.from_pretrained("microsoft/Florence-2-base-ft", trust_remote_code=True)

prompt = "<OD>"

url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/car.jpg?download=true"
image = Image.open(requests.get(url, stream=True).raw)

inputs = processor(text=prompt, images=image, return_tensors="pt")

generated_ids = model.generate(
    input_ids=inputs["input_ids"],
    pixel_values=inputs["pixel_values"],
    max_new_tokens=1024,
    do_sample=False,
    num_beams=3
)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=False)[0]

parsed_answer = processor.post_process_generation(generated_text, task="<OD>", image_size=(image.width, image.height))

print(parsed_answer)
