Spatial database manager for a multi-source image understanding system

摘要

The design of a spatial database management subsystem for an image understanding system for multi-source image processing is considered. The image understanding system is a generic knowledge-based architecture providing a basic environment for fusing spatial information from a number of sources to produce an improved image description. The database manager copes with a variety of spatial data models, including raster data from a variety of sensors and vector data from image segmentations and maps, within a tiled image format. Facilities for relating raster and vector data are provided. An image set database handles relationships between objects in images which have been fused. The database system encompasses certain low-level image processing utilities, including a data flow control module for local windowing operations, and a connected component finder.
