The counting of objects or parts is—one should think—no big challenge for image processing any more. For such applications to count objects, special attention is given to the suitable illumination, so that the contours of the object are clearly visible and to create a dividing line between the objects. Nevertheless sometimes it takes a particular skill or in the current case a combination of visual filters, which eventually make it possible to flawlessly count objects which are similar in shape and color and in addition touch each other.
