Abstract

Video scene segmentation is fundamental role for content based video analysis. In this paper, we propose a new region based video scene segmentation method using continuity test for each object region which is segmented by the watershed algorithm for all frames in video data. For this purpose, we first classify video data segments into classes that are the dynamic and static sections according to the object movement rate by comparing the spatial and shape similarity of each region. And then, try to segment each sections by grouping each sections by comparing the neighbor section sections by comparing the neighbor section similarity. Because, this method uses the region which represented on object as a similarity measure, it can segment video scenes efficiently without undesirable fault alarms by illumination and partial changes.

동영상 데이터의 장면 분할은 내용기반 분석을 위해 필요한 기초작업이다. 본 논문에서는 동영상의 매 프레임을 워터쉐드 알고리즘을 통해 객체 중심의 작은 영역들로 나누어 각 영역이 연속적인 프레임 상에서 계속 존재하는가를 파악하는 방법을 통해 장면을 구분하는 새로운 영역기반 장면 분할 기법을 제안한다. 이를 위해 각 영역들에 대한 형태와 공간상의 유사도를 측정해 영역들의 움직임 정도에 따라 동영상 데이터를 동적 구간과 정적 구간으로 나누고 인접한 구간간의 유사도에 따라 그룹화 하는 방법을 통해 장면 분할을 시도한다. 제안하는 기법은 객체들을 표현하는 각 영역을 비교 대상으로 삼기 때문에 명암 변화나 변화에도 오검출 하지 않으면서 효과적으로 장면을 구분해낼수 있는 장점을 갖는다.
