Image Pre-Processing for Maximum Accuracy

What happens before OCR? Take a look at the OCR pre-processing steps:

  • Advanced image processing methods are available to improve OCR accuracy
  • Auto inversion functionality detects if the image needs to be inverted for highest accuracy
  • Automatic image orientation detects and adjusts images so they are properly oriented
  • Deskew methods detect image misalignment and automatically correct it, improving segmentation and recognition accuracy
  • Despeckling methods remove minor dots and imperfections in the image capture process


Superior Results Processing

When you get the OCR recognition details, each character is returned with a confidence level to show accuracy. Separate word confidence values provide an additional accuracy indication. Advanced font and location information allows the OCR library to create text representations of the original file with a similar layout.

The ImageGear OCR engine processes all data in a Unicode format. The data output can be formatted for a specific code page with multiple output options such as:

  • Image over PDF
  • Text-based PDF
  • XML
