Abstract

Recently, the character recognization technique is strongly needed to enable the mobile communication devices with cameras to gather input information from the users. In general, it is not easy to reuse a CBOCR(Camera Based Optical Character Recognizer) module because of its dependency on a specific platform. In this paper, we propose a software architecture for CBOCR module providing the easy adaptability to various mobile communication platforms. The proposed architecture is composed of the platform dependency support layer, the interface layer, the engine support layer, and the engine layer. The engine layer adopts a plug-in data structure to support various hardware endian policies. We show the effectiveness of the proposed method by applying the architecture to a practical product.

최근 카메라가 장착된 이동통신기기 환경에서 사용자로부터 정보의 입력을 위한 문자 인식 기술이 많이 요구되고 있다. 일반적으로 임베디드 환경에서 개발된 광학 문자 인식기(Optical Character Recognizer) 모듈은 특정 플랫폼에 대한 의존성 때문에 재사용하기 어렵다. 본 논문은 다양한 이동통신기기 환경에 쉽게 적용될 수 있는 광학 문자 인식기를 위한 소프트웨어 아키텍처를 제안한다. 제안된 아키텍처는 플랫폼 의존 지원계층, 인터페이스 계층, 엔진 지원계층 그리고 엔진 계층으로 나뉜다. 엔진 지원 계층에서는 다양한 하드웨어 엔디안 정책에 대응하기 위해 플러그인 데이터 구조를 지원한다. 제안된 아키텍쳐의 실제적인 적용을 통해 제안된 방법의 실효성을 보인다.
