In this paper, two VQ algorithms are introduced: 1)VQ
with a Fast Clustering Algorithm (VQ-FCA) that can be
implemented for codebook production, and, 2)VQ with a
partially reordered codebook (VQ-PRCB), that extracts the
correlation between adjacent VQ indices. Based on these
algorithms, two schemes are proposed : 1)2D VQ, & 2)
combined 3D VQ schemes. Experimental results are
compared with other algorithms to show its advantages.
