DLMSearch: Diversified landmark search by photo

This paper focuses on the problem of searching for diversified landmarks with photos. More particularly, we propose a system called DLMSearch which handles image query, searches for diversified landmarks and provides representative visual summaries. DLMSearch allows a user to upload a query photo and searches for landmarks with high relevance and diversity in real time. Then DLMSearch presents a delicate photo summary for each returned landmark, considering both visual representativeness and diversity. Quantative evaluations on a web-scale landmark photo collection demonstrate the effectiveness of the DLMSearch system. Experimental results verify the merits of the proposed system. © 2012 ACM.
