<p>This paper proposes a novel solution to querying image databases by matching raster features to imagery completely in the raster/spatial domain using the shape of single features together with their spatial relations as the matching primitives. The core feature-based matching module combines a revised least-squares matching algorithm, to accomplish the matching process on binary images, with a unique implementation of a feature library that organizes and links query objects with their images in the database, thus enabling fast and efficient real-time retrieval of relevant imagery. The purpose is to extend this previous work of ours, which matches on the shape of single features only, to include querying configurations of image objects. As such, both spatial reasoning, e.g. the topological (disjoint, touching, overlapping, etc.), directional (north, south, east, etc.), and metric (distance) relationships between individual features, together with feature shape matching are r...
