Right choice is (c) Golay logic processor
To elaborate: Image Processor: The system uses two computers. The second computer is a special purpose pattern recognition computer, the Golay Logic Processor (Golay, 1969), which enables the system to transform cell pattern recognition information into differential results. Golay logic (Preston et al 1979) enables the system to ‘see’ a cell in much the same way as a technologist does.
