Archive Search System Using Image Analysis Technology

摘要

As a way to use video accumulated by broadcasters more effectively independently of manually added text data, we have been researching technology in which image analysis is used to generate metadata for video as well as search technology. We have also verified the utility of the image analysis technology using raw video from the Great East Japan Earthquake and the broadcast archives. This article describes a demonstration of linking this technology to the broadcast archive search system actually used by program producers, gives an overview of the technologies, systems and functionality, and discusses the results of analyzing evaluations and operation logs from real users.
