A class of 4-bank bisymmetric biorthogonal wavelet bases has been constructed,in which any wavelet system can be determined by its low-pass filter.Thus,the least restrictive conditions are needed for forming a wavelet so that the free degrees can be reversed for application requirement.Some concrete examples with high vanishing moments are also given,and the properities of the transformation matrix are studied.These wavelets can process the boundary conveniently,and enjoy the highly efficient computations i...
