Optical Character Recognition (OCR) .NET API

It is a standalone OCR API that enhances your .NET apps to perform the OCR operation on JPEG, PNG, GIF, BMP & TIFF images for extraction of English, French, Spanish & Portuguese content.

Aspose.OCR for .NET not only provides the Optical Character Recognition engine but more. You can also apply Blur, Gaussian Blur, and Median filter to reduce noise before document recognition and can set the OcrEngine to ignore non-textual blocks, maintain correct text order during document text recognition & automatically correct spellings of the document text.

Image OCR API Features

  • Programmatically detect, identify and read characters from images.
  • Support English, French, Spanish and Portuguese text.
  • Detect and read popular font faces such as Arial, Times New Roman, Courier New, Tahoma, Calibri & Verdana.
  • Supports regular, bold and italic font styles.
  • Scan whole image or only a specific portion of the image.
  • Scan rotated images.
  • Application of various noise removal filters to assist image recognition.

Enhancements in Version 19.9.3

  • New text recognition engine speed and quality with the introduction of a new Line Recognition Neural Network. It allows to process the entire lines of text without splitting them into separate words which makes recognition faster and with higher quality.
