二元正交对称不可分尺度函数的参数化

Let I be the 2 × 2 identity matrix, and M a 2 × 2 dilation matrix with M2 = 2I. First, we present the correlation of the scaling functions with dilation matrix M and 2I. Then by relating the properties of scaling functions with dilation matrix 2I to the properties of scaling functions with dilation matrix M, we give a parameterization of a class of bivariate nonseparable orthogonal symmetric compactly supported scaling functions with dilation matrix M. Finally, a construction example of nonseparable orthogonal symmetric and compactly supported scaling functions is given.

Parameterization of Bivariate Nonseparable Orthogonal Symmetric Scaling Functions with Short Support

Let $I$ be the $2\times 2$ identity matrix, and $M$ a $2\times 2$ dilation matrix with $M^2=2I$. First, we present the correlation of the scaling functions with dilation matrix $M$ and $2I$. Then by relating the properties of scaling functions with dilation matrix $2I$ to the properties of scaling functions with dilation matrix $M$, we give a parameterization of a class of bivariate nonseparable orthogonal symmetric compactly supported scaling functions with dilation matrix $M$. Finally, a construction example of nonseparable orthogonal symmetric and compactly supported scaling functions is given.
