Abstract Binarization of digital holograms is used for storage and on-line transfer of registered information and for optical reconstruction of images using binary digital micromirror devices. The capabilities of binarization of optically registered holograms by iterative methods with application of the error diffusion method either at each step of varied binarization threshold or only at the final iteration are considered. The variation of method parameters is analyzed and the quality of reconstructed images is compared with the quality of the binarized holograms. It is determined that the method with application of the error diffusion operation only at the final stage increases the quality of image reconstruction by 12 $$\%$$ compared to the one-step methods.

使用误差扩散方法对数字全息图进行迭代二值化

摘要 数字全息图的二值化用于注册信息的存储和在线传输，以及使用二进制数字微镜设备对图像进行光学重建。考虑了通过在不同二值化阈值的每个步骤或仅在最终迭代中应用误差扩散方法的迭代方法对光学配准全息图进行二值化的能力。分析了方法参数的变化，并将重建图像的质量与二值化全息图的质量进行了比较。确定仅在最后阶段应用误差扩散操作的方法与一步法相比将图像重建质量提高了 12 $$\%$$。
