a novel method to design the Daubechies filter is introduced.Based on this
an algorithm of the image perfect decomposition and reconstruction is proposed.In fact
for orthogonal wavelet transform
the padding approach to the boundary condition is periodic.The approach is derived from the design method of Daubechies filter.When the signal length is more than the length of the filter
the signal can be decomposed and reconstructed perfectly.
