Abstract :
An optical cosine transform system is designed using computer generated holograms and a phase-conjugate mirror which can provide segmented transform images fulfilling the specification laid down by the CCITT H.261 recommendation on Video Audiovisual Services. The system is evaluated using computer simulations
