Signal and Data Processing

The population of elderly people has growing trend in the developed or developing countries. Since the elderly are mainly associated with disability, this group of people exposed to dangerous events such as falling down. It is therefore needed to take care of these people against dangerous events. Intelligent video monitoring is a approach that may be able to give quick notification to the caregivers. For this purpose, in this paper, an approach using a novel tracking method based on modified contour algorithm is presented. The new method is able to conduct tracking and falling down detection in a realistic conditions in the presence of multiple motions. Simulations indicate that the proposed algorithm is able to identify the fall-down event with high accuracy and speed.
