Document Image Cleanup and Pre-processing SDK Technology


To further enhance document-imaging technologies such as OCR, barcode and forms recognition, LEAD has developed a large collection of advanced document-image processing functions for .NET (C# & VB), C/C++, WinRT, iOS, macOS, Java, and web developers. This powerful collection of functions can rid scanned documents of artifacts and imperfections such as hole punches, skewed angles, borders, and dust specks. Clean black and white images improve recognition accuracy, optimize processing speed, and improve lossless compression ratios, all of which are essential to any document-imaging workflow.

Overview of LEADTOOLS Document Image Cleanup and Pre-processing SDK Technology

  • Powerful functions to pre-process document images for OCR, MICR, OMR, ICR, barcode, and forms recognition
  • Image cleanup and noise reduction functions improve document-image readability and compression performance
  • Advanced color detection and conversion functions identify optimal bit depth and palette to preserve image quality while reducing file size
  • Use region of interest to isolate specific parts of images
  • Document-image cleanup and pre-processing SDK technology is available for .NET (C# & VB), C DLL, C++, WinRT, iOS, macOS, Android, Linux, Silverlight, and as Web Services
  • Multithreaded support for document-image processing in high performance server-based applications hosted as Windows services and web services
