In this Paper an approach of frequency-domain filtering has been Proposed toimplement mathematical morphologjcal centroid scale-space optical-eleCtronic hybrid imageparallel transformation, in which the filter has ben designed and made by means of CGH (computer generated holograms). This filter is used as a structure element of themathematical morphological centroid scale-sauce optical- electronic hybrid image parallelProcessing system. The binary and grey level imase centroid scale-space transformation has been implemented using this approach.
