摘要： A debris flow is a serious natural disaster which can occur anywhere whether in a valley or on a mountain slope, destroying everything it passes through. Debris flows can occur suddenly and cause residents in the path to suffer casualties and property loss. An early warning system is necessary to reduce the damage in order to protect human life and personal property. However, most debris flow detection systems, like wireless sensors, satellite images and radar, are not suitable for general public use. Vision surveillance systems are generally erected in Taiwan as public devices for security. Therefore, we propose a novel debris early warning system that uses a computer vision technique and build a simulation environment to prove the feasibility. 其他題名： Nat Hazards 出版者： Dordrecht: Springer Netherlands 出版日期： 2013-06-01 出處： Natural hazards (Dordrecht), 2013-06, Vol.67 (2), p.783-796 資源來源： Agricultural & Environmental Science Collection 版權： Springer Science+Business Media Dordrecht 2013 版權： 2014 INIST-CNRS 識別號： ISSN: 0921-030X 識別號： EISSN: 1573-0840 識別號： DOI: 10.1007/s11069-013-0605-2 識別號： CODEN: NAHZEL
