In this paper, we present a new multiple regions and their spatial relationship-based image retrieval method. In this method,
a semantic object is integrated as a set of related regions based on their spatial relationships and visual features. In contrast
to other ROI (Region-of-Interest) or multiple region-based algorithms, we use the Hausdorff Distance (HD) to estimate spatial
relationships between regions. By our proposed HD, we can simplify matching process between complex spatial relationships
and admit spatial variations of regions, such as translation, rotation, insertion, and deletion. Furthermore, to solve the
weight adjust problem automatically and to reflect user’s perceptual subjectivity to the system, we incorporate relevance
feedback mechanism into our similarity measure process.
