SPIRE: A progressive content-based spatial image retrieval engine

In this demo, we will show the implementation of a content-based SPatial Im age Retrieval Engine (SPIRE) for multimodal unstructured data. This archite cture provides a framework for retrieving multi-modal data including image, image sequence, time series and parametric data from large archives. Drama tic speedup (from a factor of 4 to 35) has been achieved for many search op erations such as template matching, texture feature extraction. This framew ork has been applied and validated in solar flares and petroleum exploratio n in which spatial and spatial-temporal phenomena are located.
