Figure 4

All three illustrations were prepared using the MATLAB function imagesc and its default color scale. Left: Original depth image, showing the fur-covered model on the wooden plate. It was mounted on a board. Middle and Right: The subsequent image processing steps. Middle: A rectangle has been added to the depth image. This modification of the original software was necessary to prevent the image from being deleted, because the models in contrast to real cows did not reach the image’s lower edge. Afterwards the automated segmentation has set all background to zero (blue). Right: The backbone (black line), ischeal tuberosities, dishes of the rump and tail (white dots) and BB30 (point on the backbone in 30 pixel radius from the tail, white rectangle) have been determined automatically.
