Creating Visual Summaries for Geographic Regions
نویسندگان
چکیده
Queries for place names represent a hefty chunk of Web image searches. Generic image retrieval solutions do not use any geographic information to improve the results for queries with place names, while systems like Flickr Places [3] or Panoramio [11] exploit raw georeferencing information to illustrate places. In this paper, we present a method for generating informative and diversified visual summaries (photographic representations) of places by using a geographical gazetteer. The gazetteer is built from user-contributed data and its content reflects a communitybased perception of places. We evaluate our image retrieval method against Flickr and Flickr Places and show that the obtained results are significantly improved compared to these two baseline applications.

متن کاملSynthesizing Evocative Imagery through Design Patterns
Automatically creating images that give a sense of content can be useful in a number of settings. Such images can summarize a larger collection of media in novel ways, giving an evocation of the whole, rather than a precise linguistic summary. Paradoxically, such visual summaries are often found to be more useful as indicators of the gestalt of a media than more traditional language summaries. ...
