    MethodQuality of Reconstructed Image/AdvantagesDisadvantages
    Spatial multiplexing[1113,15]High/computationally efficientOnly half of the display area is utilized Complicated optical setting involving high-resolution grating
    GS or iterative Fresnel transform[16,17]High/computationally intensiveComputationally intensive Suitable for 3D scenes comprising of small number of plane images
    Complex modulation[18]High/computationally efficientRequires optical filtering
    OSPR[19]Good/computationally intensiveReconstructed image contaminated with noise Requires generation of multiple hologram frames to attenuate the noise
    Error diffusion[20,21]High/computationally efficientIntensity of reconstructed image is low
    SPOH[25]Good/computationally efficientLines and edge patterns are degraded
