A Novel Coding Scheme Based on Wavelet Transform and Visibility Factors for Still Images
LOU Zhe,LI Yi-bing. A Novel Coding Scheme Based on Wavelet Transform and Visibility Factors for Still Images[J]. Journal of Harbin Engineering University, 2000, 21(4): 69-72
Authors:LOU Zhe  LI Yi-bing
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
