Forms processing and optical marks recognition (OMR) technology is widely used for classification, routing and recognition by templates of forms of electronic documents like invoices, waybills, etc; recognition of optical marks filled into a form of test, questionnaire, ballots, etc.

VintaSoft Forms Processing .NET Plug-in allows to identify and align a document image to match the known template and recognize optical marks, text and barcodes in the document form.

Plug-in features

• The plug-in can be used for developing .NET 10, .NET 9, .NET 8, .NET 7, .NET 6 applications (console, WPF, WinForms, ASP.NET Core, service, etc) for Windows
• The plug-in can be used for developing .NET 10, .NET 9, .NET 8, .NET 7, .NET 6 applications (console, ASP.NET Core, service, etc) for Linux and macOS
• The plug-in can be used for developing .NET Framework 4.8, 4.7, 4.6, 4.5, 4.0, 3.5 applications (console, WPF, WinForms, ASP.NET MVC, ASP.NET WebForms, service, etc) for Windows
• The plug-in core is written in C#
• AnyCPU, x86 and x64 mode support
  
• Create a form template, which defines blank (not filled) form
  • Create a form template
  • Edit (add, change or remove) fields of form template
  • Define custom fields of form template - architecture is open
  • Serialize form templates into XML, deserialize form templates from XML
  
  
• Edit (add, change or remove) fields of form template in WinForms or WPF image viewer
  • Edit (add, change or remove) fields of form template in WinForms image viewer
  • Edit (add, change or remove) fields of form template in WPF image viewer
  • Automatically detect not filled quadritical and circular OMR fields on a form template in image viewer
  • Customize the visual appearance of form template fields
  
  
• Create an imprint of form template and completed form
  • Create an image imprint based on lines, L search pattern or user defined algorithm
  
  
• Identify a completed form from known form templates by comparing imprints of form template and completed form
  • Compare 2 image imprints. The algorithm can compensate distortions, which are related with displacement, scale or rotation
  • Identify an image from a set of known templates and get the transformation matrix from image to the template image
  
  
• Align a completed form to match its form template
• Recognize completed form
  • Recognize completed forms synchronously or asynchronously
  • Recognize completed forms in multiple threads
  • Recognize optical marks (OMR) and bubble sheets in completed form
  • Recognize text fields with typed text in completed form - VintaSoft OCR .NET Plug-in is necessary
  • Recognize text fields with handwritten digits in completed form - VintaSoft OCR .NET Plug-in is necessary
  • Recognize barcode fields in filled form - VintaSoft Barcode .NET SDK is necessary
  
  
• Display recognized completed form in WinForms or WPF
  • Display recognized completed form above form template (aligned or not aligned) in WPF image viewer
  • Display recognized completed form above form template (aligned or not aligned) in WinForms image viewer
  • Customize the visual appearance of recognized completed form
