<p>A monitoring system for monitoring the behaviour of an object, the monitoring system having at least one image sensor and being operative to extract variables from image sequences input from the one or more image sensor, wherein the variables are interrelated such that certain combinations of values of variables occur frequently and other combinations of values of variables do not occur during normal behaviour of the object, the values of variables and relationships between the variables are recorded by the monitoring system as a reference set of data, and after the values of the variables and the relationships between the variables have been recorded for a predetermined training time, an event is triggered by the system when an unusual combination of values of variables occurs.</p> |
