LayoutLM DocVQA x PaddleOCR

What is LayoutLM DocVQA x PaddleOCR ?

LayoutLM DocVQA x PaddleOCR is a powerful tool designed to extract text from scanned documents. It combines the capabilities of LayoutLM, a pre-trained model for document visual question answering, and PaddleOCR, a robust OCR (Optical Character Recognition) system. This integration enables accurate text extraction from images of documents, leveraging advanced layout understanding and text recognition technologies.

Features

• Advanced Layout Understanding: Captures the spatial structure of text in documents, enabling context-aware text extraction.
• Multi-Language Support: Recognizes text in multiple languages, making it versatile for global document processing.
• High Accuracy OCR: Utilizes PaddleOCR's state-of-the-art text recognition capabilities for precise text extraction.
• End-to-End Processing: Seamlessly processes document images from input to structured text output.
• Pre-Trained Models: Built on pre-trained models for reliable performance without requiring extensive manual training.

How to use LayoutLM DocVQA x PaddleOCR ?

1. Install Required Packages: Install PaddleOCR and LayoutLM libraries to access the combined functionality.
2. Load Pre-Trained Models: Load the LayoutLM model for document layout analysis and PaddleOCR for text recognition.
3. Preprocess the Image: Input the scanned document image and apply necessary preprocessing steps.
4. Detect Text Regions: Use LayoutLM to identify text regions within the document.
5. Extract Text: Apply PaddleOCR to extract text from the identified regions.
6. Parse and Structure Text: Combine and format the extracted text into a readable output.

# Example usage:
from paddlexOCR import PaddleOCR
from layoutlm import Document

# Initialize models
ocr = PaddleOCR(lang='en')
document = Document.from_file("document.pdf")

# Process document
text_regions = document.analyze_layout()
extracted_text = ocr.ocr(text_regions)

# Output the result
print(extracted_text)
