Abstract

This paper presents a new indexing technique, for the fast content-based image browsing and retrieval in a database. By applying the rosette pattern that has more sample lines in the vicinity of center than those m the outer parts, we can get global gray distribution features as well as local positional information. These features are transformed into histogram and used as database indices. From the simulation results, the proposed method clearly shows the validity and the efficiency in respect of memory space as well as a good retrieval performance.

본 논문에서는 영상에 대해 영상 중심 부분에 주사가 집중되는 특정을 지닌 로젯 패턴을 적용함으로써 영상의 전체적인 그레이 분포 특징뿐만 아니라 국부적인 위치 정보까지 얻을 수 있으며 이를 히스토그램 분포 특성으로 변환시켜 데이터베이스의 색인 정보로 저장한 후, 입력되는 질의 영상에 대해 사용자가 원하는 검색 결과를 제시하는 방법에 대해 제안한다. 실험 결과 제안된 방법이 검색에 있어 우수한 성능을 갖추고 또한 색인에 필요한 메모리 공간을 크게 줄일 수 있음을 확인하였다.
