A novel method of designing better TSVQ codebooks

A novel method based on hyperplane tests is introduced for the design of binary tree structured vector quantisation (TSVQ) codebooks. A hyperplane test is a simple technique to decide on which side of the hyperplane any given point is. This technique is used in our method to find the closest codeword for each training vector. From the experimental results, it is shown the method we propose not only designs better TSVQ codebooks but also requires less computational cost than that of the traditional scheme.
