 Abstract: In this paper we present a modification of the well-known LBG algorithm for the generation of codebooks in vector quantization. Our algorithm, denoted as the ILBG algorithm, reduces the codebook error of the LBG algorithm drastically in typical applications. In our experiments we were able to achieve up to 75\,\% reduction of the codebook error in only a few additional iteration steps. In the context of lossy image compression this error reduction leads to an increase of\/ 2--3~dB of the peak-signal-to-noise-ratio (PSNR) in turn.
