DOI: 10.1109/jstqe.2020.2996657
Abstract: Conventionally, a digital micromirror device (DMD) can only perform binary amplitude modulation of a light field. Simultaneous amplitude and phase modulation with a DMD is achieved by our proposed error diffusion scheme with a 4f… read more here.

DOI: 10.1109/tim.2023.3236340
Abstract: The error diffusion algorithm shows great potential in binary defocusing fringe projection profilometry (FPP) for improving the intensity representation of binary patterns. However, the fixed kernel in the error diffusion algorithm makes the generated binary… read more here.

DOI: 10.1109/tip.2018.2815181
Abstract: In this paper, we carry out a performance analysis from a probabilistic perspective to introduce the error diffusion-based halftone visual watermarking (EDHVW) methods’ expected performances and limitations. Then, we propose a new general EDHVW method,… read more here.

DOI: 10.1364/oe.477816
Abstract: Holographic retinal projection display (RPD) can project images directly onto the retina without any lens by encoding a convergent spherical wave phase with the target images. Conventional amplitude-type holographic RPD suffers from strong zero-order light… read more here.

DOI: 10.3788/col202119.050501
Abstract: The bidirectional error diffusion (BERD) algorithm is free from random phase modulation that introduces speckle noise on the reconstructed images, compared with other computer-generated phase-only hologram (POH) approaches. During the POH generation process, the amplitudes… read more here.
