Product Architecture

The OmniPage Capture SDK architecture is designed to accommodate multiple image processing technologies through four main subsystems:

  • An image input subsystem for scanning or importing images.
  • An image preprocessing subsystem for improving image OCR quality prior to recognition.
  • A recognition subsystem that provides multiple recognition technologies for image processing.
  • An export subsystem to format the output from multiple recognition modules into a common format for conversion to popular word processing formats or text.

Two programming interfaces are available with the OmniPage Capture SDK:

  • C/C++ API
    The C/C++ API allows control over image input, image preprocessing, recognition, and output and supports image processing on a page basis.
  • Professional Visual Toolbox
    In conjunction with the ActiveX interface, a set of controls, collectively called the Professional Visual Toolbox, is available as an add-on module. Pre-made controls allow developers to reduce development time and speed time-to-market by allowing plug-in interfaces for your application.
    • ActiveX
      An ActiveX interface is provided for Visual C++ and Visual Basic programmers. This interface includes all of the functionality of the C interface and offers document processing capabilities allowing programmers to create solutions that manage documents more efficiently. This interface also expands the support of modern development environments, including managed environments like VB.NET or C#.
    • Pre-Made Controls
      • Image viewing
      • Zone content validation
      • Image thumbnail viewing
      • Text verification and editing
      • Display statistical information and a draft of the document
      • Provide details and progress about the workflow being executed on the system
      • Create OmniPage compatible workflows
      • Access and change output converter settings
      • Display and edit form fields and attributes

  • Delivers everything you need for scanning, OCR, ICR, OMR, barcode, PDF, and document conversion
  • Enables developers to provide higher value to customers with new and enhanced functionality
  • Provides an easy-to-use API to shorten development cycles and accelerates time to market
  • Helps your organization differentiate itself from the competition with the most advanced scanning, OCR, and PDF technologies.

Form processing made easy

OmniPage Capture SDK 20 significantly expands our form processing technologies. It now includes the new Form Template Editor, a powerful tool that helps create, modify, test and manage form templates. It also includes more powerful function calls for reliable template matching and convenient form data extraction.

Improved recognition

This new release also delivers significant Asian accuracy improvements—for example, layout accuracy has increased by 45% for all Asian languages and the character accuracy is up to 40% better. OmniPage Capture SDK 20 has also added a Thai OCR engine.

Image processing: convert all the data— even what you can hardly see

OmniPage Capture SDK now delivers a number of improvements in processing of cameras and smartphones images using the EXIF information from the cameras. With a plethora of new algorithms for automatic resolution estimation, shading correction, and new camera image workflows, OmniPage Capture SDK 20 helps make sure images are processed so that as much as possible information can be detected and converted into text.

Faster, easier and more intuitive developer experience

OmniPage Capture SDK 20 also provides many powerful user and developer experience enhancements, such as streamlined installation, an intuitive and easy-to-use Distribution Wizard, more convenient and productive APIs and settings, and much more.

Output: work with the format you prefer

With support for PDF/A-1a, PDF/A-2a, PDF/A-3a, b, u (in addition to the existing PDF A/2-b and PDF A/2-u support), OmniPage Capture SDK 20 can help you improve compliance with government and industry standards.

New Document Classifier

Documents exist in many different types and layouts and it is a common task to identify and categorise them based on their diverse contents. The new Document Classifier module enables users to separate different documents and sort them based on layout and/or textual similarities. This intelligent and trainable tool can be used in a wide range of business processes, such as email forwarding, mail-room automation, spam filtering, form processing and data extraction.
