Abstract. In this paper we discuss general requirements for parallel
implementations of image processing algorithms. Of special importance
are the communication demands in the parallel system which are de
termined by the algorithm under consideration. These communication
demands are decisive for determining the best way to distribute the im
age data to the network processors. Analysing these factors for some
typical image processing algorithms reveals that it is difficult to find a
fixed network structure which meets all the demands equally well. A
possibility to cope with these problems is to embed different topologies
into a fixed network structure. The mentioned factors were guidelines for
the design of the general purpose Parallel Image Processing System P i ps .
We describe the structure of this software package and elucidate for some
