We consider the properties of optimal xed-rate and entropy-constrained scalar quantizers for nite alphabet sources. In particular, w econsider conditions under which the optimal s...

Any quantization introduces errors. An important question is how to suppress their visual effect. In this paper we present a new quantization method for the geometry of 3D meshes,...
