摘要

Traveling experience sharing has become pervasive. In this paper, we present a system which automatically generates a multimedia travelogue for mobile users. Multimedia travelogue shows user footprint with photos on the corresponding location on the map, which could offer the space distribution inner or between the locations. Meanwhile, location overviews with representative tags and images show comprehensive knowledge of the landmarks. The key challenges are: 1) when mapping footprint, some photos are without geo-tags; 2)user-contributed photos may be not clear and graceful; 3) to detect which landmark is actually on the photo to offer location overview. We solve these challenges by combining both geo-tags and tags to estimate the location. First we use the relationship of timestamp and geo-tag in the same trip group to estimate the footprints. Second we localize the landmark on the photo by tag match method which matching user tags with representative tags of the landmark. Experimental results on a Flickr image collection of nearly 2 million images of 6,581 users demonstrate the effectiveness of our approach.
