Archival and retrieval of symbolic images: An invariant scheme based on triangular spatial relationship
2003
Pattern Recognition Letters
In this paper, a novel scheme for representing symbolic images in a symbolic image database (SID) is proposed. The proposed scheme is based on triangular spatial relationship (TSR) [Pattern Recognition Lett. 22 (2001) 999 ]. The scheme preserves TSR among the components in a symbolic image by the use of quadruples. A SID is created through the construction of B-tree, an efficient multilevel indexing structure. A methodology to retrieve similar images for a given query image is also presented.
