개요

본 논문은 장문 비디오에 대한 질문 응답에서 다중 모달 대규모 언어 모델(M-LLM)의 성능을 향상시키는 경량 M-LLM 기반 프레임 선택 방법을 제안합니다. 기존의 균일 샘플링 방식은 중요한 정보 손실을 야기할 수 있기에, 본 논문에서는 사용자 질의와 관련성이 높은 프레임을 선택적으로 추출하는 방법을 제시합니다. 이는 M-LLM을 이용한 공간적 신호(단일 프레임 중요도 점수)와 LLM을 이용한 시간적 신호(여러 프레임 선택, 모든 프레임 자막 사용)라는 두 가지 감독 신호를 통해 학습된 프레임 선택기를 사용합니다. 선택된 프레임은 고정된 다운스트림 비디오 M-LLM에 전달되어 시각적 추론 및 질문 응답을 수행합니다. 실험 결과, 제안된 방법은 다양한 비디오 질문 응답 벤치마크(ActivityNet, NExT-QA, EgoSchema, LongVideoBench)에서 다운스트림 비디오 LLM의 성능을 향상시키는 것으로 나타났습니다.
