Optimal Geometric Matching for Patch-Based Object Detection [PDF]

open access: yes, 2007
We present an efficient method to determine the optimal matching of two patch-based image object representations under rotation, scaling, and translation (RST).

Decentralized Limited‐Feedback Multiuser MIMO for Temporally Correlated Channels

open access: yesJournal of Electrical and Computer Engineering, Volume 2010, Issue 1, 2010., 2010
This paper proposes a novel multiuser (MU) multiplexing scheme for temporally correlated multiple‐input, multiple‐output (MIMO) channels, suitable for systems employing low‐rate feedback links. A decentralized solution is obtained by the mobile receivers, which employ interference rejection combiner (IRC) linear filters and command the update of the ...

Prediction error image coding using a modified stochastic vector quantization scheme [PDF]

open access: yes, 1996
The objective of this paper is to provide an efficient and yet simple method to encode the prediction error image of video sequences, based on a stochastic vector quantization (SVQ) approach that has been modified to cope with the intrinsic decorrelated ...

Magnification Control in Self-Organizing Maps and Neural Gas [PDF]

open access: yes, 2006
We consider different ways to control the magnification in self-organizing maps (SOM) and neural gas (NG). Starting from early approaches of magnification control in vector quantization, we then concentrate on different approaches for SOM and NG. We show

A new approach to texture coding using stochastic vector quantization [PDF]

open access: yes, 1994
A new method for texture coding which combines 2-D linear prediction and stochastic vector quantization is presented in this paper. To encode a texture, a linear predictor is computed first.

Multiresolution vector quantization [PDF]

open access: yes, 2004
Multiresolution source codes are data compression algorithms yielding embedded source descriptions. The decoder of a multiresolution code can build a source reproduction by decoding the embedded bit stream in part or in whole.
