  In VQ based image compression technique has three major steps namely (i)
Codebook Design, (ii) VQ Encoding Process and (iii) VQ Decoding Process. The
performance of VQ based image compression technique depends upon the
constructed codebook. A widely used technique for VQ codebook design is the
Linde-Buzo-Gray (LBG) algorithm. However the performance of the standard LBG
algorithm is highly dependent on the choice of the initial codebook. In this
paper, we have proposed a simple and very effective approach for codebook
initialization for LBG algorithm. The simulation results show that the proposed
scheme is computationally efficient and gives expected performance as compared
to the standard LBG algorithm.
