Abstract:
1. A computerized method of cropping a three dimensional representation of a face for electronic processing wherein said method is available on and implemented on an appropriate computer readable medium or firmware and executed on a computer using an operating system, said method comprising: a. selecting a first geodesic contour about an invariant reference point on said three dimensional representation of said face, b. setting a region within said first geodesic contour as a first mask, c. selecting a second geodesic contour about a boundary of said identified first region, d. setting a region within said second geodesic contour as a second mask, and e. forming a final mask from a union of said first mask and said second mask, said final mask thus providing a cropped portion of said representation of said face as a union of regions defined by at least two geodesic contours; and f. exporting said representation of said face on to an appropriate computer readable medium or firmware executable by a computer using an operating system.
