Model Card for YOLOv8s Table Detection

Model Summary

The YOLOv8s Table Detection model is an object detection model based on the YOLO (You Only Look Once) framework. It is designed to detect tables, whether they are bordered or borderless, in images. The model has been fine-tuned on a vast dataset and achieved high accuracy in detecting tables and distinguishing between bordered and borderless ones.

Model Details

Model Description

The YOLOv8s Table Detection model serves as a versatile solution for precisely identifying tables within images, whether they exhibit a bordered or borderless design. Notably, this model's capabilities extend beyond mere detection – it plays a crucial role in addressing the complexities of unstructured documents. By employing advanced techniques such as bounding box delineation, the model enables users to isolate tables of interest within the visual content.

What sets this model apart is its synergy with Optical Character Recognition (OCR) technology. This seamless integration empowers the model to not only locate tables but also to extract pertinent data contained within. The bounding box information guides the cropping of tables, which is then coupled with OCR to meticulously extract textual data, streamlining the process of information retrieval from unstructured documents.

We invite you to explore the potential of this model and its data extraction capabilities.

Furthermore, the YOLOv8s Table Detection model is not limited to table detection alone. It is a versatile tool that contributes to the processing of unstructured documents. By utilizing advanced bounding box techniques, the model empowers users to isolate tables within the document's visual content. What sets this model apart is its seamless integration with Optical Character Recognition (OCR) technology. The combination of bounding box information and OCR allows for precise data extraction from the tables. This comprehensive approach streamlines the process of information retrieval from complex documents.

User collaboration is actively encouraged to enrich the model's capabilities. By contributing table images of different designs and types, users play a pivotal role in enhancing the model's ability to detect a diverse range of tables accurately. Community participation can be facilitated through our platform or by reaching out to us at info@foduu.com. We value collaborative efforts that drive continuous improvement and innovation in table detection and extraction.

Uses

Direct Use

The YOLOv8s Table Detection model can be directly used for detecting tables in images, whether they are bordered or borderless. It is equipped with the ability to distinguish between these two categories.

Downstream Use

The model can also be fine-tuned for specific table detection tasks or integrated into larger applications for furniture recognition, interior design, image-based data extraction, and other related fields.

Out-of-Scope Use

The model is not designed for unrelated object detection tasks or scenarios outside the scope of table detection.

Bias, Risks, and Limitations

The YOLOv8s Table Detection model may have some limitations and biases:

• Performance may vary based on the quality, diversity, and representativeness of the training data.
• The model may face challenges in detecting tables with intricate designs or complex arrangements.
• Accuracy may be affected by variations in lighting conditions, image quality, and resolution.
• Detection of very small or distant tables might be less accurate.
• The model's ability to classify bordered and borderless tables may be influenced by variations in design.

Recommendations

Users should be informed about the model's limitations and potential biases. Further testing and validation are advised for specific use cases to evaluate its performance accurately.

How to Get Started with the Model

To begin using the YOLOv8s Table Detection model, follow these steps:

pip install ultralyticsplus==0.0.28 ultralytics==8.0.43

• Load model and perform prediction:

from ultralyticsplus import YOLO, render_result

# load model
model = YOLO('foduucom/table-detection-and-extraction')

# set model parameters
model.overrides['conf'] = 0.25  # NMS confidence threshold
model.overrides['iou'] = 0.45  # NMS IoU threshold
model.overrides['agnostic_nms'] = False  # NMS class-agnostic
model.overrides['max_det'] = 1000  # maximum number of detections per image

# set image
image = '/path/to/your/document/images'

# perform inference
results = model.predict(image)

# observe results
print(results[0].boxes)
render = render_result(model=model, image=image, result=results[0])
render.show()
