· CARMEN Automatic Number Plate Recognition Engine

The core of CARMEN is an image processing software module (or software library) that interprets the content of raw visual data, extracts the important information and converts it into "computer understandable" format within a fraction of a second. The proprietary image recognition and OCR technology of Adaptive Recognition Hungary is embodied in this computer program. The CARMEN Engine provides the ability to read virtually any license plate in the world.
The CARMEN Engine has no user interface (GUI) but it has an Application Programming Interface (API) as the Engine has been designed to be integrated into application and to serve as an automatic number plate recognition service.
· Software Development Kit (SDK)
The SDK is a rich collection of tools, utilities and well-documented, self-explaining sample programs. It serves as a step-by-step guide on "how to integrate the ANPR Engine into your application". There are several C/C++, Visual C/C++, Visual Basic and Delphi programs in source code. For easy integration the SDK contains ActiveX interface for Visual Basic, and Components for Delphi.
It takes 15-30 minutes (!) for a programmer to create her/his first plate recognition application around the CARMEN ANPR Engine.
