NTT Service Evolution Laboratories is conducting research and development on new media-processing technologies to enable natural interaction by presenting information that influences the visual senses. This article introduces our current research and development of a media-processing technology for improving the accuracy of depth maps by combining depth estimation with image segmentation and a system that uses this technology to generate HiddenStereo (a technology developed by NTT Communication Science Laboratories) images, which enables natural three-dimensional viewing from monocular two-dimensional images. © 2021 Nippon Telegraph and Telephone Corp..
