An information processing function peculiar to peripheral vision
Authors: Nagano Takashi 
Published: July 2007

AbstractPeripheral vision is important in the human visual function and permits observation of the objects apart from the line of focus. Most of the peripheral vision functions are still unknown. This paper reports on the detectability of a stimulus pattern at the center of the visual field and at the periphery of 23° from the center, which is affected by the coexistence of another pattern. It is found that the isolated stimulus pattern is easily detected at the periphery, in contrast to the center. It is also found that when stimulus patterns form a cluster the cluster as a whole is more easily detected, but detection of the individual patterns forming the cluster is difficult if they are small.
Design of a nonlinear feature extractor using a clustering
Authors: Okada Toshihiko , Tuwaki Tutomu , Tomita Shingo 
Published: July 2007

AbstractNonlinear feature extraction methods for pattern recognition have been proposed. Fukunaga [9] and Otsu [7] have shown that the a posteriori probability function is optimum as the nonlinear feature extraction function for the discriminant analysis or least mean‐square error estimation. However, it is a theoretical function which is considered as a kind of goal to be achieved. As an alternative, this paper proposes a distance function F(x, ω) which behaves similarly to the a posteriori probability function. The value of F corresponds to the distance between the pattern x and the pattern class w. The number of classes to be recognized is 2. In the method, the multidimensional pattern x is transformed into a two‐dimensional vector y = (y1, y2) whose components are the distance to the classes ωi, i = 1, 2, i.e., yi = F(x, ωi), i = 1, 2. The interactive display is fully utilized in the design and evaluation of F. Once F is designed based on the design pattern sets, the design patterns are all transformed into y for evaluation of F, and the result is displayed on the screen. The adequateness of F is determined by the observation of y on the screen and the value indicating the separability of the two classes. If the choice of F is not adequate, the class representation is modified, and F is redesigned through the interactive processes. Through such interactive procedures, F is improved gradually, eventually arriving at the optimal design.
Objective evaluation model of telephone transmission performance for fundamental transmission factors
Authors: Osaka Naotoshi , Kakehi Kazuhiko 
Published: July 2007

AbstractA model to estimate the opinion scores for overall satisfaction level of speech quality is an effective tool in designing telephone networks and equipment. This paper proposes a telephone transmission performance evaluation model named OPINE. It deals with fundamental factors (loss, noise, room noise, frequency band limitation) that degrade telephone transmission performance. Three psychological factors affecting performance are selected: 1) impairment of speech for band limitation; 2) effective loudness loss or excess of speech; and 3) noisiness during speech interval and non‐speech interval. After finding PI (Performance Index) that expresses the degradation degree of performance for each factor from the spectra of sound and noise in the ear, MOS (Mean Opinion Score) is predicted. The model was applied to the experimental data. As a result, it is shown that the predicted MOS agrees fairly well with the subjectively evaluated MOS, where the standard deviation between these is 0.28.
A qualitative investigation of time‐invariant nonlinear networks. Global state equation existence criteria
Authors: Suzuki Yoshihiko 
Published: July 2007

AbstractThis paper defines that globally there exists a state equation when a dynamical system of time‐invariant nonlinear network can be described only by capacitor voltages and inductor currents. A sufficient condition is presented for the state equation to exist globally. A sufficient condition is also shown for the state equation to exist globally, if the capacitor voltage and the inductor currents are replaced by capacitor currents and inductor voltages. Then the effect of the parasitic resistance or parasitic reactance on the existence of the state equation is discussed. When only parasitic resistances are added, the existence of the global state equation is preserved. However, the existence of the global state equation based on the capacitor currents and the inductor voltages is related to the eventual passivity of the original network. The latter half of this paper discusses the effect of perturbation of the branch characteristics constituting the network on the existence of the global state equation. Especially, it is shown that when the element is strictly locally passive, both the existence of the global state equation and the strictly local passivity are not affected by the perturbation.
On approximation of low‐pass type band‐limited waves by interpolation
Authors: Kida Takuro 
Published: July 2007

AbstractAn approximation method is proposed for a class of band‐limited waveforms whose Fourier spectra F(ω) are confined in the interval ‐ω1 ≦ ω ≦ ω1. The side lobes of such waveforms are also small in the range of 0 < ω0 < ∥ω∥ < ω1. First, the approximation waveform is obtained from summation of the product of an interpolating function and the sampling value f(tk) at the sampling point tk (k = 0 ∼ K). One objective of the proposed method is to find an interpolating function that will minimize the envelope of a family of approximation waveforms, which is used as a measure of error associated with the approximation. The optimum interpolating function, also satisfies the condition of discrete orthogonality. The proposed approximation technique also piovides convergence to the actual waveform with respect to a set of sampling points determined by the conventional sampling theorem. The approximation error is evaluated and weighted in the frequency domain using Fourier series expansion. The lower and upper bounds of approximation error in the frequency domain are derived and their relationships to the original waveform are established.
Dynamic multistage vector quantization of images
Authors: Murakami Tokumichi , Itoh Atsushi , Asai Kohtaro 
Published: July 2007

AbstractThe research and development of low bit‐rate high‐efficiency coding methods for teleconferencing are progressing in many directions. In the recent paper, dynamic multistage vector quantization is proposed to reduce both temporal and spatial redundancy of motion pictures. First, a dynamic vector quantization algorithm is proposed exploiting the correlation due to the almost periodic nature of the input signal. In addition, the clustering process of the motion vector is investigated in relation to dynamic codebook generation. Next, based on statistical properties of the residual image signal, an adaptive vector quantization with mean separation and normalization is described, and a multistage structure is introduced. The computer simulation results relating to the proposed dynamic multistage vector quantizer show about 37 dB SN ratio at 0.15 ‐ 0.2 bit/pixel for actual motion images.
