The application of feature integration and relevance feedback in medical image retrieval

First,multi-feature integration is proposed based on the study of single feature image retrieval techniques ? color feature of gray histogram,texture feature of wavelet transform and shape feature of invariant moments.Then,with the relevance feedback mechanism,users could not only control the retrieval procedure,but also obtain satisfying retrieval results by adjusting relevance weights.Finally,the precisions and recalls of single feature,multi-feature integration and relevance feedback are calculated and compared.
