The paper introduces the design of a wavelet transform software package,i.e.WYUWave.WYUWave implements most of the commonly used basic functions on wavelet transform,including convolution,forward and inverse wavelet transform of both one dimensional and two dimensional signals,various orthogonal and biorthogonal filter design,the calculation of wavelet functions and scaling functions,multiresolution analysis etc.The design of WYUWave is based on C/C++ and can be divided into three layers with the second and...
