The recent growth of data intensive digital audio, image, and video applications, have not only sustained the need for more efficient ways to compress images but have made compression of such signals central to image-storage technology and digital communications. Data transfer of uncompressed video over digital networks requires very high bandwidth. The state-of-the-art image compression techniques may exploit the dependencies between the subbands in a wavelet transformed image. In this paper, a modified version of LBG algorithm using Partial Search Partial Distortion is presented for coding the wavelet coefficients to speed up the codebook generation. The proposed scheme can save 70 - 80 % of the Vector Quantization encoding time compared to fully search and reduced arithmetic complexity with out sacrificing performance.
