1. A human detector for use in detecting a human in a scene, the detector comprising:

  • a first camera sensitive to a first band of wavelengths within a reflected infrared radiation range and operable to provide a first image output representative of the scene;

    a second camera sensitive to a second band of wavelengths within the reflected infrared radiation range and operable to provide a second image output representative of the scene;

    a fuser connected to said first and second cameras operable on the first image output and the second image output to provide a fused image output having an increased contrast between a human and a background in the scene;

    a thresholder connected to said fuser operable on the fused image output for use in segmenting a detected human from the scene, the thresholder providing a thresholded output; and

    an image indicator connected to said thresholder and operable on the thresholded output to detect a human in the scene.
