A Three-Layered Graph-Based Learning Approach for Remote Sensing Image Retrieval

 A Three-Layered Graph-Based Learning Approach for Remote Sensing Image Retrieval

 With the emergence of huge volumes of highresolution remote sensing images produced by all sorts of satellites and airborne sensors, processing and analysis of these images require effective retrieval techniques. To alleviate the dramatic variation of the retrieval accuracy among queries caused by the single image feature algorithms, we developed a novel graph-based learning method for effectively retrieving remote sensing images. The method utilizes a three-layer framework that integrates the strengths of query expansion and fusion of holistic and local features.
