PCA를 이용한 데이터베이스 검색에 있어서의 최적 MPEG-7 디스크립터 조합에 관한 연구
A study of optimal MPEG-7 descriptor composite in database searching using PCA
초록
When we search database with a query image, the retrieval efficiency will vary from each kind of descriptor. Even the best representative descriptor, it results a few useless images that don't match with query image. This type of error can be reduced by adopting another descriptor which extracts features in different way. At present, the choice of descriptors is base on intuitive and experimental method. By theoretic accessing to the problem of descriptor choice, we can solve the given problem in the objective and rational way. In this study, we intend to make a composite of descriptors that can reduce retrieval error by adopting principal component analysis.
