本文研究了与行列式为±2的二阶伸缩矩阵相关的多分辨分析尺度空间上的混淆现象,给出了这类混淆误差的傅里叶变换的表达,从而得到这类混淆误差的最优点态估计.
This paper addresses the aliasing error for a class of two-dimensional multiresolution analysis associated with a dilation matrix of determinant ±2. The explicit expression of the Fourier transformation of the aliasing error is established, from which we obtain an optimal point estimation of the aliasing error.
