A motion detection techniqueis presented which exhibits robust properties suitable for general operation in a surveillance environment. The technique is sensitive to transient perturbations present in an image seuqnce while being insensitive to temporal clutter. Its performance is robust to scale and offset variations in the input sequence. The system is implemented as a pixel based temporal recursive filter, whih requires modes computational resources to process each new input frame. Analysis of filter properties and expeirmental results for a real image seuence are reported.
