Abstract
Monitoring an individual to determine when the individual is likely to exit a supportive structure. An apparatus has an image capturing device that captures successive images of the monitored individual in the supportive structure. A processing device compares a current captured image to a previous image to detect predetermined characteristics of the monitored individual with respect to the supportive structure. An alarm is actuated when it is determined that the detected predetermined characteristics exceed predetermined threshold values for at least one of the predetermined characteristics.
