Abstract

One of the challenges that has been faced by holographic 3D display is the lack of 3D contents. To deal with the shortage of 3D contents, a 2D-to-3D algorithm is presented for the holographic 3D display. The 2D images are firstly classified into 3 categories by the features. The depth maps for different categories are obtained by different calculation models accordingly. The computer-generated holograms (CGHs) are calculated by the layer-based angular-spectrum approach. These CGHs can be reconstructed with obvious 3D depth cues in simulations and experiments.
