Design of Piecewise Uniform Scalar Quantizer with Geometric Progression of Segment Width

Optimal nearly uniform scalar quantizer design for wavelet coding

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Average Complexity Analysis of Scalar Quantizer design

In this paper an exact and complete analysis of average design complexities of Lloyd-Max's scalar quantizers, scalar compandors and scalar quantizers designed using the hybrid model is carried out. The average design complexity depends on arithmetic complexity, memory complexity and implementation complexity. It is demonstrated that for a fixed number of quantizaton levels N, scalar compandors ...

An algorithm for uniform vector quantizer design

A vector quantizer maps a k-dimensional vector into one of a finite set of output vectors or “points”. Although certain lattices have been shown to have desirable properties for vector quantization applications, there are as yet no algorithms available in the quantization literature for building quantizers based on these lattices. An algorithm for designing vector quantizers based on the root l...

Multiproduct Uniform Polar Quantizer

The aim of this paper is to reduce the complexity of the unrestricted uniform polar quantizer (UUPQ), keeping its high performances. To achieve this, in this paper we propose the multiproduct uniform polar quantizer (MUPQ), where several consecutive magnitude levels are joined in segments and within each segment the uniform product quantization is performed (i.e. all levels within one segments ...
