1. A method for image ghost removal comprising:

  • receiving an image and a first background model related to the image;

    generating a foreground mask based only on the image and the first background model;

    identifying image ghosts within the foreground mask; and

    updating the first background model to eliminate the image ghosts without comparing the image to a second background model, wherein the identifying image ghosts entails a determination of an array of counts for each pixel in the image containing a number of seconds that the pixel has been continuously flagged as part of the ghost image in the foreground mask,and wherein the identifying image ghosts further entails measuring an amount of motion within the image ghosts to ensure that the image ghosts are not a foreground element.
