%X Using normalization,vanishing moment of biorthogonality symmetry filter and the 9/7 wavelet lift construct,a new method is proposed for constructing lifting wavelets family whose coefficients consisted of two free variables.The lift coefficient and the filter coefficient obtained using our method are very succinct of which the coefficients' denominators are the index of the two.Under the filter theory,the biorthogonality and vanishing moment is discussed.Furthermore,the characteristic of C9/7 is compared to the well-known original irrational coefficients 9/7 wavelet filters developed by Cohen,Daubechies and Feauveau.The software simulation result show that the new method is optimal because of the low complexity in the computation of image coding and keeping the quality of the image after compressed.
