초록

온라인 미디어 플랫폼의 발전 및 코로나19 사태로 디지털 영상 콘텐츠의 양산과 소비가 급증하고 있다. 이용자들은 디지털 영상 콘텐츠를 선택하기 위해 썸네일, 티저 영상 등을 통하여 짧은 시간에 콘텐츠를 파악하고 본인에게 맞는 디지털 영상 콘텐츠를 선정하여 시청하고 있다. 세계 곳곳에서 생산되는 모든 디지털 영상 콘텐츠를 일일이 확인하고, 이용자가 선택할 수 있게 티저 영상을 수작업으로 편집하는 것은 매우 불편한 작업이다. 본 연구에서는 티저 영상을 자동으로 생성하기 위해 YCbCr 컬러 모델을 기반으로 키프레임을 추출하고, 클러스터링 기법을 통해 추출된 키프레임을 최적화한다. 마지막으로 최종 추출된 키프레임을 연결하여 사용자들의 디지털 영상 콘텐츠 확인을 도와 주기 위한 티저 영상을 제작하는 방법을 제시한다.

Due to the development of online media platforms and the COVID-19 incident, the mass production and consumption of digital video content are rapidly increasing. In order to select digital video content, users grasp it in a short time through thumbnails and teaser videos, and select and watch digital video content that suits them. It is very inconvenient to check all digital video contents produced around the world one by one and manually edit teaser videos for users to choose from. In this paper, keyframes are extracted based on YCbCr color models to automatically generate teaser videos, and keyframes extracted through clustering are optimized. Finally, we present a method of producing a teaser video to help users check digital video content by connecting the finally extracted keyframes.
