  • 摘要:A computer-generated pseudo hologram was synthesized using the complex Hadamard transform instead of the Fourier transform used to synthesize a computer-generated hologram. As a result, an image was reconsurcted through ae simulation, and a result that was similar result that from to the Fourier transform was obtained for the binary phase quantization, although a physical image (optical reconstructed image) was obtained. In addition, we propose the application of computer-generated pseudo holograms, which are used to hide the confidential information in a dither image. The strength of a StirmMark attack on a dithered image embedded with computer-generated pseudo holograms is weaker than the results of that using the Fourier transform hologram. It was previously reported that there was the possibility of the use of the computer generated holograms for information security.
