ImageLocalization CombinedwithSOM forColor-Based ImageRetrieval

A newtechnique toimprove theperformance ofcolor basedimageretrieval isproposed Theproposed technique consists oftwomajorphases. Inthefirst phase, theSOM-self Organizing Map-isusedtocluster images database based onsomeprimitive features ofthe image. Theresult obtained through thefirst phaseis usedasafiltered setofimages tobefedinto thesecond phasewhichrelies on thefeature extracted and compared based onimagelocalization topreserve the spatial similarity between search imageandimages database. Theproposed approach overcomes the computational complexity of applying bin-to-bin comparison asamulti dimensionalfeature vectors inthe original color histogram approach.
