| Abstract: | A novel coding algorithm was presented for still image using biorthogonal wavelet transform.Combined with the visibility preaccentuation before the quantization,a new data structure named extended Q_tree was proposed to organize wavelet transformation coefficients.Experimental results show that the new algorithm is very practical and with good performance. |

| Keywords: | wavelet transform extended Q_tree entropy coding |
