RealROI: Discovering Real Regions of Interest From Geotagged Photos
Kwang Woo Nam, KwangSoo Yang · IEEE Access · 2022
Given a set of geotagged photos with a view direction, the discovering real regions of interest (DRRI) problem involves identifying real regions of Interest (RealROI) in the photos. The problem is important in many practical applications, such as tourist route recommendation and travel advertising. Much work has been conducted to utilize geotagged photos to discover regions of interest or routes and to provide recommendations according to similar preferences. However, these approaches are not ideal for identifying regions of interest (ROI) because the usage of geotagged photos is limited to the GPS coordinates of the photo. This paper proposes novel algorithms to discover real regions of interest in photos based on the direction in which the photos were taken.
