Abstract

Thispaper we provide two example cases for this purpose andstudy the performance of IFD in the conventional sequentialsignature file (SSF) method and a new vertical partitioningenvironment, the multiframe signature file (MFSF) method,that we introduced in our recent study [10, 11, 18]. For thispurpose we developed a test environment and implementedthe SSF and MFSF methods. We extended these methodsto use IFD and tested their performance with real data. Theexperiments show that IFD...
