OCR / MICR

Show in webframe

The award winning LEADTOOLS OCR Modules provide methods for incorporating optical character recognition (OCR) technology into an application and include everything needed to develop robust, high performance and scalable document imaging solutions that include optical character recognition technology.

An important feature of the OCR design is the support of multiple OCR engines. The ability to choose the right engine for a specific solution gives unprecedented flexibility to developers. To reduce complexity and overall development time, the design hides the underlying engine details through the use of a common .NET class library. Changing underlying OCR engines based on the requirements of the project requires virtually no change to the application code.

In addition, LEAD also offers a wide range of functionality that may be added to LEADTOOLS as needed. These advanced features include barcode detection, recognition and printing, forms registration, recognition and processing, Optical Mark Recognition (OMR), and handwritten text recognition (ICR).

Key Features:

Convert an image to a document with as little as three lines of code.
OCR images from SharePoint.
Process an entire page or only specific areas in a page.
Recognize and export text, choosing from any of 40 formats , including * Adobe PDF and PDF/A , MS Word, MS Excel as well as various flavors of ANSI and UNICODE text.
Perform OCR processes in a single or multi-threaded environment with optimization for server-based operations.
Create, process and recognize multiple documents simultaneously in the same application.
Supports 32 and 64 bit development.
Multiple OCR engines are supported and abstracted from the user through the use of a common .NET class library. Switching between the various engines requires virtually no changes in the application code.
Select the character set and language dictionary of documents to be recognized. Choose from English, Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, or Swedish.
Segment complex pages manually or automatically (using AutoZone technology) into text zones, image zones, table zones, lines, headers and footers.
Set accuracy thresholds prior to recognition to control the accuracy of recognition.
Recognize text from 5 to 72 points in virtually any typeface.
Increase recognition accuracy with built-in and user dictionaries.
Automatically detect fax, dot matrix, and other degraded documents and compensate accordingly.
Process both text and graphics. The recognition software's ability to distinguish halftone graphics from text can provide the basis of a compound document processing system.
High-level design provides ease of use, while available low-level functions are still available to provide complete control.

OCR Modules:

Each of the following LEADTOOLS OCR Modules include interfaces that greatly simplify coding and speed development of OCR applications. Additionally, the same code can be used with any of the LEADTOOLS OCR Modules.

The Plus and Pro versions of the LEADTOOLS OCR module include several OCR subsystems. These OCR subsystems are utilized internally to apply powerful two- and three-way voting techniques to ensure the most accurate results possible. Additionally, the Plus and Pro versions include state-of-the-art auto image enhancements to ensure high performance and low error rates for any type of image composition or source including faxed and dot matrix printed images.

Supported OCR Output Formats:

The LEADTOOLS OCR Engine can deliver precise coordinate, confidence and attribute data for each recognized character, giving the application great control over the formatting of the output text - at one extreme mirroring the input document, at the other permitting a unique user-defined style.

LEADTOOLS OCR supports the output of many different file formats, including:

Adobe PDF *	Displaying the generated PDF file in a PDF-reader results in a very similar look to the original document. The text can be searched. The PDF file contains the recognized characters in the same positions as in the original.
Text - Standard	Text output with line break after each line. If table is present, its cells are positioned by TABs
Text - Smart	Text output with line break after each line. Left margin is taken into account (with SPACEs) If a table is present; its cells are positioned by SPACEs.
Text - Stripped	Text output with line break after each paragraph. If table is present, its cells are separated by TABs.
Text - Plain	Text output with line break after each line. Left and Upper margins are is taken into account (with SPACEs and NEWLINEs) If table is present, its cells are positioned by TABs.
Text - Comma Delimited	Comma delimited text output. Line/cell contents are surrounded by quotes (""). The default delimiter (comma) can be overridden.
Text - Tab Delimited	TAB separated text output. Line/cell contents are surrounded by quotes ("")
Rec ASCII (Formatted)	Text output, layout retention with mimicked SPACEs. Line/cell contents are surrounded by quotes ("")
Rec ASCII (Standard)	Text output allowing quick text conversion.
Rec ASCII (StandardEx)	Text output allowing quick text conversion. Line break after each line and after each zone.
General Word Processor	Text output allowing quick text conversion. Line break after each paragraph.
HTML 3.2	HTML output. HTML 3.2 is useful to export with partial formatting. The output files support both IE and Netscape.
