초록

실감형 미디어를 구성하기 위해서는 다시점 영상 또는 비디오들로 구성된 대용량의 콘텐츠가 필수적이다. 이러한 콘텐츠는 다량의 카메라들을 목적에 따라 배치하여 획득하므로 영상 구성의 복잡성과 콘텐츠의 크기가 급격히 커진다는 문제점을 갖고 있다. 3D 미디어 환경에서 카메라의 개수를 최소화하면서도 목적에 맞게 다양한 시점을 제공할 수 있는 가상시점 영상 생성은 핵심적인 기술이다. 본 기고문에서는 다시점 영상과 비디오로부터 학습 기반의 가상 시점 영상 생성 연구들에 대해 체계적인 조사를 통해 그 결과를 다음과 같이 제시한다. 첫째, 가상 시점 영상 생성에 대한 배경 개념을 정의한다. 둘째, 제안하는 분류 방식에 따라 기존의 제안된 방법들을 상세하게 분석한다. 셋째, 가상 시점 영상 생성에 주로 사용되는 관련 데이터셋을 조사한다. 마지막으로는 각 연구들이 갖고 있는 특징들을 분석하고, 정량적, 정성적 평가 결과를 비교한다.
