摘要：Smoking in elevators would give children and weak women a deadly blow. Latest no- smoking laws and increasing the price of cigarettes decreased smoking rate drastically. However, since this phenomenon is a transient one, the smoking rate seems to be increasing again to the previous level. In our research, we above all chose people who smoked in elevators. The method of sampling key frame is Average Intensity Measure. This method uses average intensity of whole image for each RGB color channel in order to detect scene change. If white color (255) occurs by a certain pixel after reducing the subject domain of sampled key frame to face domain, it is considered as smoking. These extracted scenes could be provided as a evidence of forensics in police stations or courts.
