Welcome to the world of PDF document layout analysis! In this article, we’ll walk you through the steps to segment and classify different components of your PDF documents using the powerful tools available in the PDF Document Layout Analysis service. Whether you’re dealing with texts, titles, images, or tables, we’ve got you covered.
What is PDF Document Layout Analysis?
The PDF Document Layout Analysis service breaks down PDF pages into meaningful segments, identifying various elements and their types while determining the order they appear. Imagine reading a complex book; if each chapter was printed on a separate page, you’d need a method to sort and identify those chapters, titles, figures, and tables to comprehend the content effectively. That’s what this service does for PDFs!
Getting Started
To kick off your journey, you have two different ways to run the service, depending on whether or not you have GPU support:
- With GPU support: Run the following command in your terminal:
docker run --rm --name pdf-document-layout-analysis --gpus device=0 -p 5060:5060 --entrypoint ./start.sh huridocs/pdf-document-layout-analysis:v0.0.14.1 - Without GPU support: Use this command instead:
docker run --rm --name pdf-document-layout-analysis -p 5060:5060 --entrypoint ./start.sh huridocs/pdf-document-layout-analysis:v0.0.14.1
Extracting Segments from a PDF
Once the service is up and running, extracting segments from a PDF becomes a breeze! Use the following command to get started:
curl -X POST -F file=@PATHTOPDF/pdf_name.pdf localhost:5060To stop the server, simply use:
docker stop pdf-document-layout-analysisUnderstanding the Models
In the context of our PDF document layout analysis, you can think of the models as two specialized assistants:
- Visual Model (VGT) – Trained by the Alibaba Research Group, this model sees the entire page, providing comprehensive context.
- LightGBM Model – This model works with XML information extracted from the PDF, making it faster and more resource-friendly, albeit less comprehensive.
Optimizing Usage
When invoking the service, you might want to use the visual model for the best results:
curl -X POST -F file=@PATHTOPDF/pdf_name.pdf localhost:5060If you prefer the LightGBM model for quick extraction, use this command instead:
curl -X POST -F file=@PATHTOPDF/pdf_name.pdf -F fast=true localhost:5060The output will provide a list of segments with detailed information such as position, dimensions, and types.
Troubleshooting Tips
Here are some common issues you may encounter and their solutions:
- Service Not Starting: Ensure Docker Desktop is properly installed and running. Check for version compatibility.
- High Resource Usage: If you’re experiencing lag or crashes, consider using the LightGBM model which is less resource-intensive.
- Output Errors: Double-check that the correct paths to your PDF are specified in the commands.
