Smoothing of inter-layer edge artifacts in depth-map computer-generated holograms

초록

In the depth-map computer-generated hologram (CGH), inter-layer edge artifacts are observed in the discontinu-ous edges of section-wise depth-map objects. CGH synthesis, utilizing the hybrid smoothing method of silhouette mask-ing and edge-apodization, alleviates unwanted inter-layer edge artifacts. The proposed method achieves improved de -artifact filtering that generates holographic images closer to the ground truth image of the depth-map object unattain-able by the conventional CGH synthesis method.(C) 2022 Optica Publishing Group
