- A new fast vector quantiser (VQ) is proposed which reduces
computational complexity by searching the intersection of search
regions defmed by triangular inequalities for multiple anchors. A
greedy algorithm which selects an anchor set is also proposed.
The proposed VQ reduces the number of multiply operations by
24.4% compared to Li's VQ  while preserving the same
encoding quality as the full-search VQ.
