LEADTOOLS OCR Module - LEAD Engine C API Introduction

Summary

The LEADTOOLS OCR Module - LEAD Engine C API extends the functionality of LEADTOOLS SDKs by providing properties, methods, and callbacks for easily incorporating optical and magnetic ink character recognition (OCR / MICR) into applications. Superior OCR processing speeds are exceptionally useful in form recognition and processing applications.

Key Features

• Recognize a variety of documents, including facsimiles, photocopies and documents with complex layouts.
• Select the language to be recognized, and recognize multiple languages within one document. Choose from English, Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, or Swedish.
• Recognize text from 5 to 72 points in virtually any typeface, and export to more than 40 different text, MS Word, MS Excel, PDF and more.
• Recognize special characters, such as MICR (Magnetic Ink Character Recognition), including bank routing indicators, check amounts, and customer account numbers.
• PDF and PDF/A output, ICR and OMR support is also available.
• Recognize multiple document pages at once and save recognition result to a single file.
• Add page(s) to internal OCR list of pages or add them directly on temporary LTD file on disk to save you system memory (which is the recommended approach).
• Process both text and graphics.
• Each document may contain multiple OCR zones.
• Segment complex pages manually or automatically into text zones, image zones and table zones.
• Recognize text and colors.
• Auto-orientate documents for improved recognition.
• Correct document characteristics such as noise, darkness, lightness to achieve the best possible character recognition.
• Increase recognition accuracy with built-in lexical classes and user-defined lexicons (dictionaries).
• Set desired accuracy (confidence) thresholds prior to recognition to balance speed and accuracy of recognition.
