ToggleOCR (Optical Character Recognition):
OCR is a technology used to convert different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data. It extracts text from these documents, making it possible to digitize and process the information contained within them.
Key Features of OCR (Optical Character Recognition)
- Text Extraction: Converts scanned documents, images, or PDFs into editable and searchable text formats.
- Document Digitization: Enables the conversion of paper-based documents into digital formats for easier storage and retrieval.
- Data Entry Automation: Automates data entry tasks by extracting text from invoices, forms, receipts, and other documents.
- Basic Layout Recognition: Recognizes basic document layout elements such as paragraphs, headings, and tables.
- Language Support: Supports recognition and conversion of text in multiple languages.
- Accessibility: Enhances accessibility by converting printed text into readable formats for visually impaired individuals.
- Integration: Often integrated with other software for document management systems and business applications.
- Speed: Provides fast text recognition and conversion, improving efficiency in document processing workflows.
- Accuracy: Offers high accuracy in text recognition, although results may vary based on document quality and clarity.
- Cost-Effectiveness: Generally more cost-effective for basic text extraction and document digitization tasks.
Azure Document Intelligence:
Azure Document Intelligence, part of Microsoft Azure’s AI and machine learning services, goes beyond traditional OCR capabilities.
