摘要
我们首先介绍了B-样条及基样条,然后用m阶的B-样条N_m(x)功生成了一个L ̄2(R)中一个比例为r的多分辨逼近,而且用构造了相应的小波空间,这里L_(2m)为2m阶的基样条,最后,我们给了小波的分解与合成算法。
We first introduce the B-spline and the fundamental interpolatory spline,then we take m ̄(th) order B-spline N_m(x)generating a multiresolution approximation with scaling rate r of L ̄2(R) and use constructing the wavelet spaces, where L_(2m)is (2m) ̄(th) order fundamental interpolatory spline. Finaliy, we giye the wavelet decomposition and reconstruction algorithms.
