Automatic geotagging for personal photos with sharing images on social media networks

Abstract

The information of location for digital photos is important for users to recall memory and retrieve photos with interested events. Geotagging is the process of identifying geographical metadata to digital photos. Since a large number of images may be generated in a journey or trip, traditional manual spatial annotation is time consuming and infeasible for personal collecting. In this paper, GPS signals on photographic devices and images of websites, or photosharing social media web are adopted to automatically identify geo-location of personal photos. We study and compare the effectiveness of two individual approaches and the combination approach. The results show that geographical coordinates are the most influential component for resolving geo-location. The geotagging process using sharing photos on social media service is also revealed and discussed.
