Revised Aggregation-tree Used in Metadata Extraction from SVG Images

Many of the multimedia researchers have focused on the issue of the retrieval of images using indexed image collections. A number of spatial data structures based on Minimum Bounding Rectangles (MBRs) have been developed. Previously, we presented aggregation-tree structure to extract metadata from Scalable Vector Graphics (SVG) documents [8]. In this paper, we revised the aggregation-tree to better model the data in SVG and reduce the size of the aggregation-tree. Aggregation-tree is constructed based on aggregation rules for different topological relations between objects. Keywords SVG image, Aggregation-tree, Object aggregation, Relation.
