The complete parametrization of orthogonal hexagonally symmetric low-pass filters with $$\sqrt{3}$$ refinement is presented for several cases of coefficient supports. Given a symmetric low-pass filter, a method that allows to construct hexagonally symmetric tight wavelet frames is suggested. Also, a framework for the construction of orthogonal hexagonally symmetric wavelets is presented.

具有 $$\sqrt{3}$$ 细化的六边形对称正交滤波器
对于几种系数支持情况,提出了具有 $$\sqrt{3}$$ 细化的正交六边形对称低通滤波器的完整参数化。给定一个对称低通滤波器,提出了一种允许构造六边形对称紧小波框架的方法。此外,还提出了用于构造正交六边形对称小波的框架。
