  annote    = {We introduce an application for the detection of
    aberrant behaviour within home based environments, with a focus on
    repetitive actions, which may be present in instance of persons
    suffering from dementia. Video based analysis has been used to
    detect the motion of a person within a given scene in addition to
    tracking them over the time. Detection of repetitive actions has
    been based on the analysis of a person's trajectory using the
    principles of signal correlation. Along with the ability to detect
    repetitive motion the developed approach also has the ability to
    measure the amount of activity/inactivity within the scene during
    a given period of time. Our results showed that the developed
    approach had the ability to detect all patterns in the data set
    examined with an average accuracy of 96.67\%. This work has
    therefore validated the proposed concept of video based analysis
    for the detection of repetitive activities.},
