  • Image tracking system and technique
    Patent number: 5329368
    Abstract: An image motion tracking system (10) for use with an image detector (12, 14) having an array of elements in the x and y directions. First, frequency domain representations of an image are created to provide a reference frame of image data and an input frame of image data. A processor (30) is included for detecting a change in phase of the detector (12, 14) with respect to first and second samples of the reference frame relative to corresponding first and second samples of the input frame to discern a displacement of at least a portion of the input frame relative to at least a portion of the reference frame. Finally, the output signal is corrected to compensate for the displacement of the input frame relative to the reference frame.
