APPARATUS FOR DETECTING OF SINGLE ELDERLY PERSONS ABNORMAL SITUATION USING IMAGE AND METHOD THEREOF

摘要

In order to detect an abnormal situation, videos taken in real time are obtained from video cameras installed in multiple areas within a house, the number of variation values between former and latter frames of the obtained videos according to pixels is calculated, the number of pixels in which a calculated variation value is over a predetermined variation value is detected, an activity amount of an object is calculated by accumulating the number of the pixels detected within a predetermined time range, the calculated activity amount is stored corresponding to previously classified date and time slot, the value of the calculated activity amount and the value of a previously stored activity amount are compared, occurrence of an abnormal situation is determined based on a difference value between the compared activity amounts, and an activity amount which is in the same time slot as a currently calculated activity amount among previously stored activity amounts is detected and compared.
