| Abstract: | The concepts of two-direction refinable function and two-direction wavelet are introduced by Professor Yang Shouzhi in his paper Two-direction refinable functions and two-direction wavelets with dilation factor m.The definition of the two-direction multi-resolution analysis is also given.As the more general situation of the traditional wavelet,the two-direction wavelet plays an important role in signal processing.The definition of orthogonal two-direction multi-resolution analysis is given and the fast decomposition algorithm and restructuring algorithm are shown. |
