Abstract
We propose methods to enhance an approximation quality of a local 3D mesh fragments when using LBG Vector Quantization (VQ). This paper provides an analysis of an impact of different methods of 3D mesh feature extraction to quantization distortion. Mahalanobis distance is proposed as a distortion measure in comparison to an Euclidean distance used in previous works. Mesh characteristic is obtained by randomly walking through the mesh vertexes.
