In this paper, we proposed a new algorithm based on independent keypoints databases for indoor place recognition. In analogy with set operation, a new kind of operations for keypoints sets are defined to describe the process of independent keypoints database establishment and place classification. To obtain the databases, keypoints are firstly extracted from sample images whose class are known, and...
Component technology is one of the most important parts in software reuse research field. The way how we can obtain the components accurately and efficiently is also a difficulty problem which must be solved by reasonable classification and optimal retrieval algorithm. In this paper, we present a form of components classification which is based on the facets, and realize the component retrieval method...
