Abstract: A system and method of identifying changes in behavior of a human subject comprises monitoring the movements of the subject within a space using one or more sensors, processing signals from the sensor(s) to determine values for one or more parameters associated with one or more patterns of behavior of the subject, using values for the one or more parameters accumulated over a period of time to establish one or more models of a typical pattern of behavior for the subject, monitoring the ongoing behavior of the subject to obtain current values for one or more of the parameters; and using the current values and the model(s) of a typical pattern of behavior to identify atypical behavior of the subject. An alert may be generated if the current value of one or more of the parameters is outside the acceptable limit(s). Advantageously low resolution thermal imagers are used so as to minimise intrusiveness and invasion of privacy.

Abstract: A system for monitoring the motion of objects is configured to identify objects meeting predetermined criteria appearing in a scene and to track the motion of identified objects across the scene. In a particular embodiment the system is configured to compile statistical data for multiple points or regions to indicate one or both of: the frequency with which objects are initialised at that region or point; and the frequency with which initialised objects cross the region or point. The initialisation data will indicate the areas in the scene where objects are most frequently initialised. If the statistical data shows an area of the scene in which objects are never initialised this might indicate that there is an obstruction between objects that need to be tracked and the detector. The path data will indicate the paths most frequently followed by objects.
