Abstract

When retrieving voluminous capacity of video image data, it is necessary to provide synopsized frame lists of video image data for indexing and replaying at the exact point where the user want to retrieve. We apply Mean Squared Error method to extract certain pixel value from diagonal direction of a frame. The RGB value of a pixel extracted from each frame is saved in a matrix form, and this frame is retrievedas a scene change point if the compared value of two points met the certain condition. Also implement the algorithm and provide a way to seize entire structure of video image and the point of scene changes. finally, we analyze and prove that our method has better performance compared with the others.

동영상데이터의 대용량 검색을 할 때 사용자가 원하는 검색점을 추출하여 인덱싱과 재생하기 위해서는 동영상 데이터의 프레임 리스트 제공이 필요하다. 평균오차를 적용하여 프레임의 대각선으로부터 픽셀값을 추출한다. 각각의 프레임으로부터 추출된 픽셀의 RGB값은 행렬구조로 저장하고, 저장된 프레임은 두 지정을 비교하여 장면전환점을 추출한다 또한 동영상의 전체적인 구조를 파악할 수 있는 알고리즘과 장면전환설을 구현하였다. 본 연구에서는 제안한 방법의 성능 우수성을 기존연구와 비교하여 분석하고 증명했다
