Sampling Theorems of Wavelet Subspaces with M Band in Higher Dimensions
Jin Zhou Li, Xin Cheng Zhang · Advanced materials research · 2013
Sampling theorem has a key role in signal processing and image processing. In this paper, the scaling functions with cardinal property are discussed in the dimensions and their symmetry property is classified. Therefore, sampling theorems of wavelet subspaces are obtained. Then, the cardinal orthogonal scaling function with cardinal property is characterized in the dimensions and an equation between the highpass filter coefficients and wavelet samples are got. The existing results are generalized to the case of M band.
