摘要
针对Mallat极大模重构小波变换算法没有充分利用信号突变点的不足,提出了一种改进Mallat极大模重构小波变换的方法,并以插值的形式给出了重构小波变换的显式表达式.显式表达式便于数值计算,同时也为求解一类广义微分方程提供了途径.
In this paper, the Mallat reconstruction algorithm of the wavelet transform modulus maxima is improved. The authors established a new method of reconstruction of the wavelet transform, which makes up the deficiency of the Mallat reconstruction algorithm of the wavelet transform modulus maxima and the interpolation expression of reconstruction is shown. Because the interpolation can be expressed by section, it is convenient for numeric calculation. Furthermore, the theoretic basis is provided for discussing the solution of a kind of generalized differential equation.
