1 Introduction
1.1 About OCR
OCR (Optical Character Recognition) is the technology that allows you to transform
images (e.g., images scanned from paper documents) into editable text-based
computer files.
1.2 About Asprise OCR SDK
Embedded a high performance OCR engine, Asprise OCR SDK is OCR software
development kit that can be used with VB, VB.NET, VC++, VC.NET, C#, Java, .Net,
Borland C, Delphi, etc.
1.3 Features of Asprise OCR
An incomplete list of features offered by Asprise OCR:
Highest Level of Accuracy
Asprise OCR can easily recognize difficult documents of poor image quality;
Excellent Format Retention
Text layouts on the input documents are preserved;
High Speed
Asprise OCR uses optimized OCR engine to perform excellent recognition in very
short time;
Ease of Use
We strive to make the developer's life easier. Complex parameter configurations
are removed from Asprise OCR SDK. You only have to supply the image
document. Asprise OCR can intelligently determine the best setting internally.
