本文研究了α尺度正交小波的Mallat算法,利用α重多分辨分析,得到了正交小波的分解与重构算法,给出了Haar小波的Mallat算法的矩阵表示,并简化了计算.
In this paper, we study the Mallat algorithm of orthonormal wavelets with dilation factor α. Using the theory of a multiplicity a multiresolution analysis, we get the decomposition and reconstruction algorithm of orthonormal wavelets. The matrix representation of Mallat algorithm corresponding to Haar wavelet is given, which simplifies the computation.
