摘要 因其在信号去噪、图像处理等方面的广泛应用,小波标架引起了众多数学家的关注。本文从与行列式为±2的伸缩矩阵相关的标架多尺度分析(FMRA)出发,讨论了FMRA小波标架的构造,得到了FMRA小波标架的一个明确表达式,并给出了一些例子来说明所得结论的一般性。 Motivated by its application in signal denoising, image compression, etc., wavelet frames have interested many mathematicians. In this paper, we discuss the construction of wavelet frames via a frame multiresolution analysis (FMRA) associated with a dilation matrix of determinant ±2. An explicit expression of FMRA frame wavelet is obtained. Some examples are also provided to illustrate the general theory.
