Abstract

In this paper, we propose a set of robustness indicators for immersive 360-degree video. With the full-fledged service of mobile carriers' 5G networks, it is possible to use large-capacity, immersive 360-degree videos at high speed anytime, anywhere. Since it can be illegally distributed in web-hard and torrents through DRM dismantling and various video modifications, however, evaluation indicators that can objectively evaluate the filtering performance for copyright protection are required. In this paper, a robustness indicators is proposed that applies the existing 2D Video robustness indicators and considers the projection method and reproduction method, which are the characteristics of Immersive 360-degree Video. The performance evaluation experiment has been carried out for a sample filtering system and it is verified that an excellent recognition rate of 95% or more has been achieved in about 3 second execution time.

본 논문에서는 실감형 360도 영상의 특징점 기술의 강인성 지표를 제안한다. 이동통신사의 5G 서비스가 본격적으로 서비스됨에 따라 언제 어디서든지 대용량의 실감형 360도 영상저작물을 빠른 속도로 이용할 수 있게 되었다. 그러나 DRM 해체 및 각종 영상 변형을 통해 웹하드, 토렌트 등에서 불법 유통되고 있어 저작권 보호를 위한 강인성이 지원되는 필터링 기술이 요구되고 있다. 본 논문에서는 기존 2D 영상의 강인성 지표를 응용하고 실감형 360도 영상저작물의 특징인 투영방법 및 재생 방법을 고려한 강인성 지표를 제안하였다. 본 제안을 샘플 필터링 시스템에 대하여 적용하여 성능평가를 실시하였고 약 3초대의 실행시간에서 95% 이상의 우수한 인식률을 확인하였다.
