Information hiding schemes based on
vector quantization (VQ) usually require lengthy VQ
encoding and decoding processes. In this paper, we
propose an efficient information hiding method based
on closest paired tree structure vector quantization
(CPTSVQ). The simulation result shows that the
execution time of the proposed scheme is much shorter
than that attained by previous approaches.
