An optical-vortex filament is characterized by a dark core of vanishing size and fluidlike propagation dynamics in the near-field region. This type of phase singularity does not naturally occur as an eigenmode of a cylindrically symmetric system, but it can be easily formed by computer-generated holography. The size of the core is an important attribute affecting vortex–vortex interactions with...

I detail a method for producing high quality Fourier transform holograms using a computer, laser printer, and overhead transparency film. The method should be useful for lecture demonstration and holography laboratories. Given an arbitrary holographic phase/amplitude plate, computer-generated holography attempts to find a suitable binary encoding of the (complex) transmission function of the ho...

Deep learning has been developing rapidly, and many holographic applications have investigated using deep learning. They shown that can outperform previous physically-based calculations lightwave simulation signal processing. This review focuses on computational holography, including computer-generated holograms, displays, digital We also discuss our personal views the promise, limitations futu...

A large-scaled full-parallax CGH with 4 billion pixels is produced by a polygon-based method. The CGH reconstructs a fine 3-D image and gives a large sensation of depth owing to the silhouette-masking technique. ©2007 Optical Society of America OCIS codes: (090.1760) Computer holography; (090.2870) Holographic display

We propose an efficient algorithm using layered stereogram based inverse Fresnel diffraction for 3-D computer-generated holograms. Experiments demonstrate the proposed method can reconstruct quality 3-D images with accurate depth cues. OCIS codes: (090.1760) Computer holography; (090.2870) Holographic display.

The inclusion of additional modalities into the communicative behavior of virtual agents besides speech has moved into focus of human-computer interface researchers, as humans are more likely to consider computer-generated figures lifelike when appropriate nonverbal behaviors are displayed in addition to speech. In this paper, we propose a knowledge-based approach for the automatic generation o...

Notation is a central issue in modern western music. Composers have often sought ways of expanding and refining the functionality of notation and, in doing so, have re-shaped the music that they were originally aiming to describe. Other musical traditions have used notation very differently; some have used no notation at all, and have thus created contrasting musical experiences. The role that ...

This work is an example of the interplay between computergenerated art work by a computer scientist and traditional paintings on canvas by an artist. We show that computer-generated swarm constructions can obtain great expressiveness and exhibit liveliness, rhythm, movement, tension, contrasts, organic looks, and rigid forms. These characteristics lend themselves to complement traditional paint...
