VECTOR QUANTIZATION

Residual vector quantization (RVQ) is investigated in context of quantization cell shapes and is found to produce oblong cell shapes. The presence of these oblong cell shapes are in part responsible for the degradation in performance of RVQ compared to vector quantization (VQ). …

This research focuses on the development of a novel adaptive dynamical system approach to vector quantization or clustering based on only ordinary differential equations (ODEs) with potential for a real-time implementation. The ODE-based approach has an advantage in making it po…

In this dissertation, the author illustrates the concept of partitioning the observation space to build a general class of filters referred to as partition-based (P) filters. The structure of P filters consists of two main parts; the partitioning and the associated filtering fun…
