Progressive Content-Based Retrieval from Satellite Image Archives
Overview In this paper, we have presented a scalable architecture to perform progressive content-based search from large satellite image archives. Objects at both the semantic and the feature levels are extracted to facilitate efficient and flexible retrieval. In addition, a hierarchical representation is constructed for each image. Consequently, content-based search operations can be applied hierarchically, resulting in a significant speedup. Other satellites (such as ERS-1 and Radarsat) equipped with Synthetic Aperture Radar (SAR) instruments have been used to determine the ice coverage of the Arctic and Antarctic Circles to monitor global warming.
