In present mobile communication system, low bit rate audio signal is supposed to be provided with high quality. This paper researches the mechanism exists of perceptual and statistics redundancy in spatial cues and establishes a selection model by joint perceptual and statistics characteristic of spatial cues. It does not quantize the values of spatial cues where the frequency bands can’t easil...

We have investigated the current-voltage characteristics (IVCs) of intrinsic Josephson junctions (IJJs). Recently, it is predicted that the longitudinal plasma wave can be excited by the parametric resonance in IJJs. Such an excitation induces a singularity called as breakpoint region around switch back region in the IVC. We have succeeded in the observation of the breakpoint region in the IVC ...

This document describes the hardware design of a tactile shear force display. The design parameters have been chosen by inquiries of psychophysical requirements and available actuator technologies. Furthermore the hardware setup of the prototype is described. This display will be used to investigate the perceptual effects of shear force to the human finger pulp.

In this paper we introduce a generative parametric model capable of producing high quality samples of natural images. Our approach uses a cascade of convolutional networks within a Laplacian pyramid framework to generate images in a coarse-to-fine fashion. At each level of the pyramid, a separate generative convnet model is trained using the Generative Adversarial Nets (GAN) approach [11]. Samp...

In the last decade we have witnessed a rapid development of various display technologies, as well as a rapid lowering down of prices of existing display technologies. These developments have opened up the new opportunities to deploy computer graphics in our day to day activities. One of these interesting deployments of computer graphics is “Informative Art”, which presents information in aesthe...

The rapid continuing development of 3-dimensional ultrasound imaging technologies has extended capabilities of fetal cardiac scanning beyond 2-dimensional imaging technologies and now provides a wide array of analytic possibilities. The acquisition of the 3D volume information is based on initial application of 2-dimensional imaging techniques including grey scale, Doppler, Power Doppler and B-...

In this study, a method to construct a full-colour volumetric display is presented using a commercially available inkjet printer. Photoreactive luminescence materials are minutely and automatically printed as the volume elements, and volumetric displays are constructed with high resolution using easy-to-fabricate means that exploit inkjet printing technologies. The results experimentally demons...

The purpose of this study was to provide insights into how virtual 3-D visual display systems contributed to cross-functional team collaboration in a product conceptual design review environment. During this empirical testing, three commercially available 3-D display systems [Helmet Mounted Display (HMD), Binocular Ommi-Orientation Monitor (BOOM), and stereoscopic shutter glasses with monitor] ...

This paper was presented at IS&T/SID CIC13 Conference in Scotssdale, AZ, November 7-11, 2006. Abstract Over the past twenty-five years a diversity of color display technologies has evolved to support a wide range of applications, including television receivers, computer monitors, cell phones, PDAs, automobile dashboards, aircraft instruments, and even incar and in-flight entertainment systems. ...
