Representation of Spectral Profiles in the Auditory System, II: Detection of Spectral Peak Shape Changes
(1994)
Based on the ripple analysis model outlined in Part I of this paper, predictions are made for the detection of shape changes in spectral peak profiles. Peak shape is uniquely described in terms of two parameters: bandwidth ...
Detection of Binary Sources Over Discrete Channels with Additive Markov Noise
(1994)
We consider the problem of directly transmitting a binary source with an inherent redundancy over a binary channel with additive stationary ergodic Markov noise. Out objective is to design an optimum receiver which fully ...
Adaptive Wavelet Based Image Coding
(1994)
New schemes for classification of images are suggested. An application of these methods in adaptive DCT of images is considered. A new method to combine classification and bit allocation is introduces. Also, an efficient ...
Ripple Analysis in Ferret Primary Auditory Cortex. II. Topographic and Columnar Distribution of Ripple Response Parameters
(1994)
We examined the columnar and topographic distribution of response parameters using spectral ripples and tonal stimuli in the primary auditory cortex (AI) of the barbiturate-anesthetized ferret. The ripple stimuli consisted ...
On Stochastic Approximations Driven by Sample Averages: Convergence Results via the ODE Method
(1994)
We consider a class of projected stochastic approximation algorithms drive by sample averages. These algorithms arise naturally in problems of on-line parametric optimization for discrete event dynamical systems., e.g., ...
Ripple Analysis in Ferret Primary Auditory Cortex. I. Response Characteristics of Single Units to Sinusoidally Rippled Spectra
(1994)
We compared the response properties of single units to tones and sinusoidally, rippled spectral stimuli in the primary auditory cortex (AI) of the, barbiturate-anesthetized ferret. Using two- tone stimuli, we determined ...
Representation of Spectral Profiles in the Auditory System, I: A Ripple Analysis Model
(1994)
A model of profile analysis is proposed in which a spectral profile is assumed to be represented by a weighted sum of sinusoidally modulated spectra (ripples). The analysis is performed by a bank of bandpass filters, each ...
Hierarchical Coding of High Data Rate Video for Asynchronous Transfer Mode Networks
(1994)
High data rate video is an integral part of high-quality multimedia for broadband networks. Owing to the high rate, compression of video information is required for an efficient use of network bandwidth. A hierarchical ...
Speech Coding over Noisy Channels
(1994)
This chapter contains a discussion of quantization over noisy channels. The effects of channel noise on the performance of vector quantizers are discussed and algorithms for the design of noisy-channel vector quantizers ...
Comparison of Responses in the Anterior and Primary Auditory Fields of the Ferret Cortex
(1994)
Characteristics of an anterior auditory field (AAF) in the ferret auditory cortex are described in terms of its electrophysiological responses to tonal stimuli and compared to those of primary auditory cortex (AI). Units ...
