The LEADTOOLS Recognition SDK includes the following products:

  • LEADTOOLS Imaging Pro
  • LEADTOOLS Document Imaging
  • LEADTOOLS Advantage OCR Module
  • LEADTOOLS Forms Recognition Module
  • LEADTOOLS 1D Barcode Module
  • LEADTOOLS 2D Barcode Module

The provided recognition and processing engines fully automate document classification and data extraction for known forms. The recognition engine creates unique XML data for each known form which is used to identify any form requiring recognition. The processing engine uses templates consisting of predefined fields for each known form. These fields can be defined using the Forms application included with the SDK, or developers can create their own template editor using the toolkit. Supported field types include machine and hand written characters, check boxes, filled bubbles, cross marks and barcodes.

In addition to saving the recognized data in various structured output formats such as delimited text, XML or database fields, a recognized free form document can be converted to searchable PDF for enterprise data mining.

To further enhance the accuracy of the recognition process, the Recognition SDK includes the LEADTOOLS document image clean-up engine, a set of document image pre-processing tools for deskew and despeckle, as well as line, border and hole-punch removal.

For maximum performance, forms recognition and OCR high level interfaces utilize an intelligent multi-threaded algorithm during recognition and processing and are supported in both 32 and 64 bit development.

LEADTOOLS Recognition SDK Key Features:

  • Provided as a low and high level .NET interface to create complete recognition and processing applications with very little code.
  • Full source code for an end-user Forms Recognition and Processing application and hundreds of lines of sample source code ready for copy and paste.
