Single-feature query by multi-examples in image databases

摘要

A common form of queries encountered in Content-Based Image Retrieval (CBIR) systems, such as QBIC and Virage, are query by example image (QBE). We encountered this problem in our implementation of a prototype CBIR system, called CHITRA. This system supports four layer image data model and enables high level concept definition such as SUNSET. Users can pose queries of the form "retrieve all images that have SUNSET and MOUNTAINS". We are addressing the problem of processing queries of the form "retrieve images similar to I_1, I_2 --, I_n based on color". We refer to such queries s SF-QBME. Essentially the same problem is encountered in processing high level concept queries such as "SUNSu0005T and MOUNTAINS" above. Processing of such queries has received some recent research attention.
