Lan Feng Wang, Kai Sun, Jing Ben Yin · Advanced materials research · 2011
Sampling theorem plays an important role in many fields such as signal processing and image processing. In this paper, the cardinal orthogonal scaling function with dilation factor 3 is classified by the highpass filter coefficient, thus, the sampling theorem in the wavelet subspace is obtained. Then, the symmetry property of cardinal orthogonal scaling function is discussed.
