Claim One:
1. A method for tracking a follicular unit on a body, the method comprising: determining a signature of a follicular unit in a first image of a body surface, wherein the signature comprises a plurality of characteristics of the follicular unit; determining pixel intensity data of a region of interest in the first image; determining pixel intensity data of the region of interest in a second image of the body surface taken at a different point in time relative to the first image; comparing the pixel intensity data of the region of interest in the first image with the pixel intensity data of the region of interest in the second image, splitting the first image into foreground and background sections, assigning each of the foreground and background sections a separate weight value, and utilizing the assigned weight values to predict the change in position of the follicular unit, and based on the comparison of the pixel intensity data of the region of interest in the first and the second images, the signature of the follicular unit, and the predicted change in position of the follicular unit, locating the follicular unit in the second image.
