Image quality of the computer-generated holograms are usually evaluated subjectively. For example, the reconstructed image from the hologram is compared with other holograms, or evaluated by the double-stimulus impairment scale method to compare with the original image. In previous research, we proposed image quality evaluation by peak signal-to-noise ratio and diffraction efficiency. Theory and numerical experimental results are shown on Fourier transform transmission hologram of both amplitude and phase modulation. In this paper, we compare objective evaluation method and subjective evaluation and verify validity. Subjective evaluation is performed by optical and numerical reconstructions, and objective evaluation is performed by the structural similarity index and diffraction efficiency.
