A digital micromirror device (DMD) provides 2D- and 3D-scene reconstruction by displaying diffractive and holographic optical elements. The highest frame rates (tens of thousands of Hz) can be achieved if the displayed optical elements are binarized. Except for DMD applications, hologram binarization is useful for display creation, image encryption, information compression and storage, fast 3D printing, etc. Error diffusion is one of the most qualitative implementations of hologram binarization. In this paper, three group's weighting matrices of error diffusion are analyzed: 16 standard, eight dot and six diagonal matrices. Thus, 30 error diffusion methods were used for optically recorded off-axis digital hologram binarization. The quality of the image reconstruction from the binarized holograms was compared. Direct applications of error diffusion with large weighting matrices and dot diffusion provide the highest reconstruction quality. Seven metrics were used as the error diffusion threshold. Twelve bypass directions of error diffusion were analyzed. In addition, the joint application of Otsu threshold and complex bypass directions allows us to improve the quality of hologram binarization by 15%.

数字微镜设备 (DMD) 通过显示衍射和全息光学元件提供 2D 和 3D 场景重建。如果显示的光学元件被二值化，则可以实现最高的帧速率（数万赫兹）。除 DMD 应用外，全息二值化可用于显示创建、图像加密、信息压缩和存储、快速 3D 打印等。误差扩散是全息二值化最定性的实现之一。本文分析了三组误差扩散的加权矩阵：16个标准矩阵、8个点矩阵和6个对角矩阵。因此，30 种误差扩散方法被用于光学记录的离轴数字全息图二值化。比较了从二值化全息图重建的图像质量。直接应用具有大加权矩阵的误差扩散和点扩散可提供最高的重建质量。七个度量被用作误差扩散阈值。分析了误差扩散的十二个旁路方向。此外，Otsu 阈值和复杂旁路方向的联合应用使我们能够将全息图二值化的质量提高 15%。
