Abstract

In this paper, we define the quaternion-valued multiresolution analysis of L 2 ℝ, H). We give the properties of the scaling functions, wavelet functions and their corresponding low-pass and high-pass filters, and present a sufficient condition for the existence of the quaternion-valued wavelet. By solving the system of equations, we obtain some kinds of low-pass filters and high-pass filters with short support and symmetry of smooth orthogonal wavelets. We also construct quaternion-valued wavelets of a quaternion variable on L 2 (H,H).

Keywords
