Mesh simplification using ellipsoidal schema for isotropic quantization of face-normal vectors
In this paper, we present a method for simplification of arbitrary 3D meshes that is based on Isotropic Quantization of face-normal vectors. There are three stages. Firstly, a cod...

Limited feedback with joint CSI quantization for multicell cooperative generalized eigenvector beamforming
Existing work on limited feedback for cooperative multicell beamforming quantizes the desired and interfering channel state information (CSI) using separate codebooks. In this pap...

Symmetric Trellis Coded Vector Quantization
We present here design techniques for trellis-coded vector quantizers with symmetric codebooks that facilitate lowcomplexity quantization as well as partitioning into equiprobable ...

Multilingual weighted codebooks
In this paper we present an approach for speech recognition of multiple languages with constrained resources on embedded devices. Examples of such systems are navigation systems, ...

Vector quantization and fuzzy ranks for image reconstruction
The problem of clustering is often addressed with techniques based on a Voronoi partition of the data space. Vector quantization is based on a similar principle, but it is a diffe...
