FISH: Fast Interactive Image Search in Huge Databases
Automated management of the content rich and voluminous multimedia data has attracted tremendous attention over the last decades. Any promising solution should ideally have easy web based access with intuitive querying methods and should be designed to respond with majority of relevant results within a few fractions of a seconds, from amongst millions of real images. This requires the building blocks of the solution like the user interface, representation and indexing, comparison and retrieval, learning and memorization, result presentation etc. all to perform together. Literature abounds with work focusing on small subsets of these blocks but a work unifying the blocks is missing. A practical solution requisites optimal integration all the blocks.
In FISH we present a complete end-to-end practical system for fast image search in huge databases FISH uses a query-by-example based simplistic interface which maximizes user input. Our proposal uses a set of standard MPEG-7 visual descriptors for representing images. We achieve this with a highly adaptive B+ - tree based indexing scheme which supports the inherent organization of data into similarity clusters. We also adopt a set of popular relevance feedback approaches for incremental short term learning and propose a highly suited scheme for inexpensive and adaptive inter-query or long term learning. We also use the long term learning based long term memory for adaptive improving ROI extraction from images. In our experiments FISH demonstrated commendable retrieval performance from a million real images within fractions of a second.
We present here the results from some of our major experiments while redirect the reader to the paper for a detailed discussion.
