Abstract
The 2D string, proposed by Chang et al., is a spatial index structure which preserves the information of spatial relationships in a spatial database. In this paper, two new image retrieval algorithms for 2D string are proposed. The first one improves the retrieval efficiency, while the second reduces the space requirement. The performance analysis shows that the two methods perform much better than previous works especially when the spatial database is large.
