Abstract: A system and method for hologram synthesis and processing capable of synthesizing holographic 3D data and displaying (or reconstructing) a full 3D image at high speed using a deep learning engine. The system synthesizes or generates a digital hologram from a light field refocus image input using the deep learning engine. That is, RGB-depth map data is acquired at high speed using the deep learning engine, such as a convolutional neural network (CNN), from real 360° multi-view color image information and the RGB-depth map data is used to produce hologram content. In addition, the system interlocks hologram data with user voice recognition and gesture recognition information to display the hologram data at a wide viewing angle and enables interaction with the user.

Abstract: Provided are an image system and an image reconstruction method using the same. The image system includes an image scan device, a spectrum signal generation device, and an image recovery device. The image scan device generates a magnetic particle detection signal on the basis of an induced magnetic field induced from a magnetic particle. The spectrum signal generation device transforms the magnetic particle detection signal to a detection spectrum signal on the basis of a two-dimensional Fourier transform kernel. The image recovery device generates an image signal on the basis of the detection spectrum signal and a system matrix. According to the inventive concept, a data amount for image reconstruction may be ensured.
