N2 - A novel image compression algorithm based on vector quantization (VQ) technique is proposed in this paper. Mean-residual domain adaptive resolution VQ method (AR-MVQ), which is composed of three key techniques, i.e., the resolution conversion, the block size alteration, and mean residual domain vector quantization (MVQ) can realize much superior compression performance than the worldwide standard JPEG and JPE02000. On the compression of the XGA (1024×768 pixels) natural images, AR-MVQ has realized a performance that is equal to the JPEG and the JPEG2000, Especially, the compression of the images including text exists an overwhelming performance superiority of 5 to 40 dB in compressed image quality.
