In this paper, the mean square error with block truncation coding (BTC) is analyzed to propose a classified interpolative BTC algorithm with VQ for improving the interpolative BTC with VQ [7]. The simulation results indicate that the bit rate and PSNR of this classified interpolative BTC algorithm with VQ are better than those of the interpolative BTC algorithm with VQ [7].

Keywords: image coding, block truncation coding (BTC), vector quantization (VQ), interpolative BTC (IBTC)
