The Recursion Algorithm and Achieve for Lifting Coefficients of Biorthogonal Wavelet

To make out the coefficients of the fast lifting wavelet transform,according to the specialty of lifting scheme of the biorthogonal wavelet,the recursion algorithm for calculating lifting coefficients is presented.According to the recusion expressions for the prediction process and the update process of forward wavelet,the method compares biorthogonal wavelet filter to coefficients and obtains lifting coefficients and scale factors.The illustration indicates that the lifting coefficients can be solved using the proposed method no matter that the lifting scheme is the prediction process first or the update process first.The transition of db5.3 wavelet lifting scheme is achieved at the Matlab7.0 platform by the recursion algorithm programme,and three level decomposition of image is accomplished.
