SRV-TAGS: An automatic tagging and search system for sensor-rich outdoor videos

Abstract

Tagging facilitates video search in many social media and web applications. While manual tagging is time consuming, subjective and sometimes inaccurate, auto-tagging facilitated by content-based techniques is compute-intensive and challenging to apply across domains. We have developed a complementary system, named SRV-TAGS, to automatically generate tags for outdoor videos based on their geographic properties, to index the videos based on their generated tags and to provide textual search services. The system works with our geo-referenced video management web portal, enabling users to manage, search and watch videos. Copyright 2011 ACM.
