The 2012 ICSI/Berkeley Video Location Estimation System
Jaeyoung Choi, Gerald H Friedland, Venkatesan Nallampatti Ekambaram · 2012
In this paper, we describe the ICSI/Berkeley video location estimation system presented at the MediaEval 2012 Placing Task. We describe the graphical model based framework that poses the geo-tagging problem as inference over the graph. Our algorithm jointly estimates the geo-locations of all the test videos, which helps obtain performance improve-ments over existing algorithms in the literature that process each query video independently. Our modeling provides a generic theoretical framework that can be used to incorpo-rate any other available textual, visual or audio features. 1.
