Abstract
Moving object detection is based on low illumination image data that includes distance or depth information. The vision system operates on a platform with a dominant translational motion and with a small amount of rotational motion. Detection of moving objects whose motions are not consistent with the movement of the background is complementary to shape-based approaches. For low illumination computer-based vision assistance a two-stage technique is used for simultaneous and subsequent frame blob correspondence. Using average scene disparity, motion is detected without explicit ego-motion calculation. These techniques make use of characteristics of infrared sensitive video data, in which heat emitting objects appear as hotspots.
