proper behavior in these unusual situations. Recognizing grown-up people and

legged animals of various sizes and with various styles of running, and birds (from
crows, hen, geese, turkeys, to ostrich), most of which can fly and run or hop on the
ground. This wide field of subjects has hardly been touched for technical vision
systems. In principle, there is no basic challenge for successful application of the
4-D approach. In practice, however, a huge volume of work lies ahead until techni-
cal vision systems will perceive animals reliably.
