H~2(I)空间中的离散小波变换
THE DISCRETE WAVELET TRANSFORM IN H~2(I) SPACE
【Abstract】 In this paper, a boundary scale function b(x) with a compact support is given,it improves a boundary scale function without the compact support in [1], then a multiresolution analysis (MRA) in (I) space is constructed and a discrete wavelet transform in H2(I) space which maps function’s sample values into the function’s wavelet coefficients is given, so that the wavelet interpolation function is obtained.
