In this paper, a method is suggested for retrieving pictures from a symbolic picture database system, based upon the spatial relationships among the objects in the symbolic picture. We present a nine direction lower-triangular (9DLT) matrix to represent a symbolic picture. A simple algorithm for spatial match retrieval of symbolic pictures based upon 9DLT matrices is proposed.

Keywords: Spatial match retrieval, 2D string, image databases, symbolic pictures, 9DLT matrix
