다중 객체 추적 기술은 스포츠, 문화 예술 공연, VR 등 여러 방송 콘텐츠에서 자주 사용되고 있다. 방송 영상 안에 등장하는 여러 객체들은 객체간 상호작용에 의해 가려짐, 사라짐 (Occlusion) 등의 현상이 빈번하게 발생하고, 이 경우 기존에 추적되어온 객체들의 ID 가 소실되거나 교환되는 문제가 발생한다. 본 논문에서 더 강인한 다중 객체 추적을 위해, 주 개체 뿐만 아니라 주 개체에 종속되는 하위 개체 또한 함께 추적하는 개체-쌍-추적 기법을 제안한다. 한 쌍으로 묶인 주 개체와 종속 개체의 추적 정보와 매칭 정보는 상호보완적으로 사용되어, 소실 및 교환된 ID 도 복원할 수 있는 가능성을 높일 수 있다. 본 논문에서는 재인지 성능 향상을 위한 개체 쌍 추적 기법을 기술하였고, 성능 평가를 통해 제안 방법이 재인지 성능 향상에 기여할 수 있음을 확인하였다.
