1. A thermal analysis system comprising:

  • a memory comprising a statistical thermal profile representing typical thermal behavior of each of a plurality of regions of a target scene and determined from a plurality of thermal images of the target scene over time;

    an infrared (IR) camera module capable of receiving IR radiation from a target scene and generating corresponding thermal image data representative of a heat pattern across the target scene based on the received IR radiation; and

    a processor in communication with the memory and the IR camera module and configured to;

    receive thermal image data from the IR camera module representative of the heat pattern of the target scene;

    for each of the plurality of regions in the received thermal image data, compare the thermal image data of the region to a corresponding region in the statistical thermal profile of the target scene;

    generate anomaly image data comprising a plurality of regions, each region in the anomaly image data corresponding to a respective region in the received thermal image data and representative of the degree of anomalousness of the received thermal image data with respect to the statistical thermal profile in that region; and

    generate a display image comprising the anomaly image data blended with one or more additional data streams.
