Towards precise POI localization with social media

Adrian Popescu, Aymen Shabou
2013 Proceedings of the 21st ACM international conference on Multimedia - MM '13  
Points of interest (POIs) are a core component of geographical databases and of location based services.  ...  Given a set of geotagged Flickr photos associated to a POI, close-up classification is used to trigger a spatial clustering process.  ...  It was possible to precisely find the point-based location and the radius for 704 POIs that are used in further experiments.  ...

Efficient Method for POI/ROI Discovery Using Flickr Geotagged Photos

Chiao-Ling Kuo, Ta-Chien Chan, I-Chun Fan, Alexander Zipf
2018 ISPRS International Journal of Geo-Information  
Point of interest (POI) and region of interest (ROI) are significant reference data that are widely used in geospatial applications.  ...  Attractive footprints in photos with a local maximum that is beneficial for distinguishing clusters are first exploited.  ...  Point of interest (POI) and region of interest (ROI) (also called area of interest [AOI] [9] ) are "a specific point location that is of interest [10] " and "an area within an urban environment which  ...

Geotagging in multimedia and computer vision—a survey

Jiebo Luo, Dhiraj Joshi, Jie Yu, Andrew Gallagher
2010 Multimedia tools and applications  
The presence of geographically relevant metadata with images and videos has opened up interesting research avenues within the multimedia and computer vision domains.  ...  Geo-tagging is a fast-emerging trend in digital photography and community photo sharing.  ...  For a given geo-location, many photos with view directions not pointing to the desired regions are typically returned through location-based search.  ...
