Abstract

A system design and realization for video surveillance with interframe probability distribution analyzation is presented in this paper. The system design is based on a high performance DSP professor, video surveillance is implemented by analyzing interframe probability distribution using trivariate normal distribution(weight, mean, variance) for scanning objects in a restricted area and the video analysis algorithm is decided for forming a different image from the probability distribution of several frame compressed by the standardized JPEG. The system processing time of D1$(720{\times}480)$ image per frame is 85ms and enables to process the system at 12 frames per second. An object surveillance about the restricted area by rules is extracted to 100% unless object is moved faster.

본 논문은 인터프레임 확률분포에 의한 비디오 감시 시스템 설계 구현에 관한 것이다. 시스템은 비디오 분석 알고리즘과 표준 JPEG 압축 알고리즘을 처리하기 위해 고성능 DSP 프로세서 기반으로 구현된다. 비디오 분석은 가중치, 평균, 분산의 3변량정규분포에 의한 인터프레임 확률분포 분석을 이용하여 특정 영역에 물체를 검출하는 알고리즘을 사용한다. 실험 결과, 시스템 처리시간이 D1$(720{\times}480)$ 영상 프레임 당 85ms 소요되었고 초당 12프레임 정도 처리한다. 규칙에 따른 특정영역 물체감시는 움직임 빠르지 않는 물체에 대해 100% 검출되었다.
