OBJECT-TRACKING SYSTEMS AND METHODS
First Claim
1. A method for tracking a follicular unit, the method comprising:
- identifying at least one marker in a first image, the first image including a follicular unit;
computing a signature of the follicular unit in the first image;
identifying the at least one marker in a second image;
computing a motion vector corresponding to a change in position of the at least one marker from the first image to the second image; and
using the motion vector and the signature of the follicular unit in the first image to label the follicular unit in the second image.

Abstract
A system and method for tracking, identifying, and labeling objects or features of interest is provided. In some embodiments, tracking is accomplished using unique signature of the feature of interest and image stabilization techniques. According to some aspects a frame of reference using predetermined markers is defined and updated based on a change in location of the markers and/or specific signature information. Individual objects or features within the frame may also be tracked and identified. Objects may be tracked by comparing two still images, determining a change in position of an object between the still images, calculating a movement vector of the object, and using the movement vector to update the location of an image device.
