主　　题：code vector indexing image coding lattice vector quantization 

摘      要：Code vector indexing is a key problem in lattice quantization applications. In order to solve this problem, we propose a method based on the idea of a coding table encompassing a set of points as small as possible. Our method works for both spherical and pyramidal code books. It provides a good tradeoff between computational complexity and storage requirements.
