Scalable Predictive Coding Using Coset Codes
… We propose an alternative to the conventional predictive coding of video based on the formulation of predictive coding as a variant of the Wyner-Ziv side-information problem in information theory. Through this formulation we propose the design of two video coding algorithms that encode video …

Multiple Description Video Coding and Digital Walkthrough Compression Using Coset Codes
Causal source coding is widely used for low-latency compression of real-world audio and video signals. The most prominent class of causal source codes used in this context are codes based on differential predictive coding. Differential predictive coding is ill-suited, however, for coding scenarios …

Speech recognition by computer: algorithms and architectures
… Analysis, (b) Fourier Analysis and (c) Linear Predictive Coding. The Fourier Analysis algorithm made use of the Prime-number Fourier Transform technique. The Linear Predictive Coding algorithm made use of LeRoux and Gueguen's method for calculating the coefficients. The system was organised so …

Effects of Priming on Subsequent Associative Memory: Testing Prediction Error and Attentional Accounts
The Predictive Coding framework is a general theory of brain function which proposes that the brain creates a hierarchical model of the world, with higher levels predicting, based on previous experience, inputs from lower levels (and ultimately the sensory input). This framework entails feedback …

Structures and algorithms for two-dimensional adaptive signal processing
… code modulation, interference cancellation, predictive coding, and noise suppression. Emphasis is placed both on FIR and IIR structures with primary benchmark issues being speed of convergence, computational complexity, and structural flexibility.

Streaming of Markov Sources over Burst Erasure Channels
… systems require both the sequential encoding of information sources and playback under strict latency constraints. The central focus of this thesis is on the fundamental limits of such communication systems in the presence of packet losses. In practice packet losses are unavoidable due …

Predictive image coding with Pseudo-Laplacian edge detector
Several edge-adaptive dual-mode Predictive coding systems are proposed for encoding monochrome video signals. These algorithms use the Pseudo-Laplacian edge detector to switch between the textural coding and the edge coding. The one-dimensional Song DM coder and the two-dimensional weighted average …

Implementation of a Connected Digit Recognizer Using Continuous Hidden Markov Modeling
… processor manufactured by Analog Devices. Linear predictive coding (LPC) analysis was first performed on a speech signal to model the characteristics of the vocal tract filter. A 7 state continuous HMM with 4 mixture density components was used to model each digit. The Viterbi reestimation method …
