Result example for first, subgraph isomorphism approach. It is an example of the result obtained for subgraph isomorphism approach. The query selected, obtained RAG and three nearest matching results obtained are shown. In A the selected query image inside the whole image is depicted by blue rectangle. B shows the extended regions, selected by the query, and the corresponding graph formed for the selection. C, D and E give the first three results retrieved by the graph matching algorithm (both segmented and coloured).
