Generating signatures and comparing between the breeds HF and FV cows. The left column of images shows depth maps of a HF (top) and a FV (bottom) cow’s backside recorded from top view. Everything but the cow is set to zero (blue). In the right column the signatures (top: HF cow, bottom: FV cow) generated from the corresponding depth maps in the left column are displayed. In both depth maps the center of mass calculated for the area covered by cow (nonzero) is marked. The signatures are generated by measuring the distances between center and boundary of the nonzero area. As the breed’s pelvis shapes differ and ischeal tuberosities lie more rearwards relative to the center of mass in HF than in FV cows, signatures of HF and FV cows are clearly distinguishable.
