Introduction to OCR

Optical Character Recognition (OCR) is a technology used to convert different types of documents, such as scanned paper documents, PDFs, or images taken by a digital camera, into editable and searchable data. The basic function of OCR involves scanning the text of a document and translating the characters into a code that can be used for data processing. This technology is widely used in various fields to digitize printed texts so that they can be electronically edited, searched, and stored more compactly. For instance, OCR can be used to convert printed invoices into digital form, making it easier to manage and search financial records.

Main Functions of OCR

  • Text Extraction

    Example Example

    Extracting text from scanned books to create editable documents.

    Example Scenario

    A publishing house uses OCR to digitize their vast collection of printed books, making them available in digital formats for e-readers and online libraries.

  • Automated Data Entry

    Example Example

    Converting printed forms into electronic data.

    Example Scenario

    A hospital uses OCR to digitize patient intake forms, allowing for automatic entry of patient information into their electronic health record (EHR) system, reducing manual data entry errors and speeding up the process.

  • Document Searchability

    Example Example

    Making scanned documents searchable by converting them into searchable PDFs.

    Example Scenario

    A law firm uses OCR to convert scanned legal documents into searchable PDFs, making it easier for attorneys to quickly find relevant information within large sets of documents during case preparations.

Ideal Users of OCR Services

  • Businesses and Enterprises

    Businesses can benefit from OCR by digitizing their paperwork, automating data entry processes, and improving data accessibility and searchability. This leads to increased efficiency, reduced costs, and better document management. For example, financial institutions can use OCR to process checks and invoices automatically, reducing the time spent on manual data entry and minimizing errors.

  • Educational Institutions

    Educational institutions can use OCR to digitize textbooks, research papers, and other printed materials. This enables the creation of accessible digital libraries, facilitating easier distribution of materials to students and researchers. For instance, universities can use OCR to convert printed academic journals into digital formats, making them accessible to students and faculty through the institution's online library.
