Predictive vector quantization of 3-D polygonal mesh geometry by representation of vertices in local coordinate systems

Bayazıt, Uluğ; Orcay, Özgür; Konur, Umut; Gürgen, Fikret Sadık (IEEE, 2005)

A large family of lossy 3-D mesh geometry compression schemes operate by predicting the position of each vertex from the coded neighboring vertices and encoding the prediction error vectors. In this work, we first employ ...
Spectral coding of mesh geometry with a hierarchical set partitioning algorithm

Konur, Umut; Bayazıt, Uluǧ; Ateş, Hasan Fehmi; Gürgen, Fikret Sadık (Spie-Int Soc Optical Engineering, 2008)

This work proposes a progressive mesh geometry coder, which expresses geometry information in terms of spectral coefficients obtained through a transformation and codes these coefficients using a hierarchical set partitioning ...
