A method of Area of Interest and Shooting Spot Detection using Geo-tagged Photographs

Social media sites include many photographs taken at various locations and times. As described herein, we propose a method to identify hotspots to visualize user interest using geo-tagging of photographs posted on social media sites. Hotspots are classifiable to two types based on its locations: area of interest or shooting spot. In some cases, a hotspot has relation to other hotspots. We extract and classify hotspots according to that relation based on the bias of photograph location and photograph orientation. Moreover, we classify whether an event happened or did not happen in extracted hotspots.
