Structure of Divisible Discrete Random Sets and Their Randomized Superpositions
(1991)
In this paper, we present an axiomatic formulation of Discrete Random Sets, and extend Choquet's uniqueness result to obtain a recursive procedure for the computation of the underlying event- space probability law, given ...
Time-Recursive Computation, Part II: Methodology, and Application on QMF Banks and ELT
(1993)
Recent advances in ISDN have promoted applications such as video- phone, tele-conferencing and HDTV, that demand real-time processing of large volume audio, video and speech data. Being the only refuge for this intense ...
Design and Implementation of Systolic Architectures for Vector Quantization
(1992)
Vector Quantization has emerged as an efficient data compression tool for compressing speech and image data. We develop efficient systolic architecture implementations of Tree-Search Vector Quantizers (TSVQ) and Finite-State ...
Analysis and Synthesis of Distributed Systems
(1994)
We first model and analyze distributed systems including distributed sensors and actuators. We then consider identification of distributed systems via adaptive wavelet neural networks (AWNNs) by taking advantage of the ...
On Image Deconvolution Using Multiple Sensors
(1990)
We consider the two dimensional Analytic Bezout Equation (ABE) and investigate the properties of a particular solution, based on-certain conditions imposed on the convolution kernels. The results permit the reconstruction ...
VLSI Algorithms and Architectures for Time-Recursive Discrete Sinuoidal Transforms with Applications to Real-Time Video Communications
(1992)
In this dissertation, we address the problem of developing efficient VLSI algorithms and architectures for discrete sinusoidal transforms in real-time applications for video communication systems. The major difficulty of ...
VLSI Architectures and Implementation of Predictive Tree- Searched Vector Quantizers for Real-Time Video Compression
(1992)
We describe a pipelined systolic architecture for implementing predictive Tree-Searched Vector Quantization (PTSVQ) for real- time image and speech coding applications. This architecture uses identical processors for both ...
Optimal Wavelet Basis Selection for Signal Representation
(1994)
We study the problem of choosing the optimal wavelet basis with compact support for signal representation and provide a general algorithm for computing the optimal wavelet basis. We first briefly review the multiresolution ...
Split Recursive Least Squares: Algorithms, Architectures, and Applications
(1994)
In this paper, a new computationally efficient algorithm for recursive least-squares (RLS) filtering is presented. The proposed Split RLS algorithm can perform the approximated RLS with O(N) complexity for signals having ...
Time-Recursive Computation and Real-Time Parallel Architectures, Part I: Framework
(1993)
The time-recursive computation has been proved as a particularly useful tool in real-time data compression, in transform domain adaptive filtering and in spectrum analysis. Unlike the FFT based ones, the time-recursive ...
