Application of lifting-scheme-based CDF(1,5) integer-integer invertible biorthogonal wavelet transform in progressively lossless image compression

讨论了基于双正交小波变换提升方案在图像压缩中的应用 ,研究了CDF( 1,3) ,CDF( 1,5 )双正交小波消失矩对图像压缩的影响。实验结果表明 ,在图像压缩中应尽可能选取具有较高消失矩的双正交小波 ,用CDF( 1,5 )双正交小波提升方案实现了基于整数运算的整 整可逆双正交小波变换 ,以及快速的。

Application of biorthogonal wavelet transform lifting-scheme is discussed in image compression. The effect of CDF(1,3),CDF(1,5) biorthogonal wavelet vanishing moments on image compression are researched. Experiment result indicates that the image compression suits to make the most of have more vanishing moments biorthogonal wavelet, and use CDF(1,5) lifting-scheme implemented integer-operation-based invertible biorthogonal wavelet transform and fast progressive and lossless compression.
