Extended Data Fig. 6: Illustration and evaluation of the binarization process for DMD patterns.
From: Sub-second volumetric 3D printing by synthesis of holographic light fields
a, Illustration of different binarization parameters G, corresponding to the number of binary images used for a single greyscale image. The curves of the truncation function are shown at the top. The optimized greyscale pattern for a specific angle is shown on the second row, with the corresponding optimized binary patterns shown on the third row. The simulated products by DISH are shown at the bottom. b, The signed distances of the simulated products, compared with the ground truth, corresponding to one, three and ten binary projections as a group. Curves of the root mean square of signed distances versus the number of total binary projection patterns with different binarization parameters are shown on the right.
