In this paper we discuss general requirements for parallel implementa­
tions of image processing algorithms. Of special importance are the
communication demands in the parallel system which are determined
by the algorithm under consideration. These communication demands
are decisive for determining the best way to distribute the image 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 de­
sign of the general purpose Parallel Image Processing System PIPS. We
describe the structure of this software package and elucidate for some
selected topics the implementation details. Experimental results from
