Shot Boundary Detection Using Global Decision Tree
전역적 결정트리를 이용한 샷 경계 검출
- Published : 2008.01.31
Abstract
This paper proposes a method to detect scene change using global decision tree that extract boundary cut that have width of big change that happen by camera brake from difference value of frames. First, calculate frame difference value through regional X2-histogram and normalization, next, calculate distance between difference value using normalization. Shot boundary detection is performed by compare global threshold distance with distance value for two adjacent frames that calculating global threshold distance based on distance between calculated difference value. Global decision tree proposed this paper can detect easily sudden scene change such as motion from object or camera and flashlight.
본 논문에서는 프레임들의 차이값으로부터 카메라 브레이크에 의해 발생하는 큰 변화의 폭을 갖는 경계지점을 추출하는 전역적 결정트리를 이용하여 샷 경계를 검출하는 방법을 제시한다. 먼저 지적
