Claim:
A system for tracking a feature of interest on a body, the system comprising: an interface adapted to receive a plurality of images from an image capture device, at least a first image comprising a feature of interest; a signature identification component, wherein the signature identification component identifies signature information of the feature of interest and detects at least one marker in the first image that is distinct from and has a location different from a location of the feature of interest, wherein the identified signature information is unique to the feature of interest and comprises a plurality of characteristics of the feature of interest; a marker referencing system, wherein the marker referencing system defines a frame of reference corresponding to the at least one marker, determines whether the at least one marker is in a second image taken at a different point in time relative to the first image, adjusts the frame of reference corresponding to a change in position of the at least one marker from the first image to the second image, and searches in a direction and within a predetermined distance from a motion vector corresponding to the adjusted frame of reference to locate the feature of interest in the second image using the identified signature information of the feature of interest.
