摘要
探讨了小波空间的不规则采样问题,证明了当采样集满足适当的采样条件和小波空间的尺度函数满足 某些条件时,对于小波空间的函数,可以由它的采样值稳定和惟一地重建。
The irregular sampling in wavelet subspaces is discussed, suppose the scaling function has some properties, one kind of sampling conditions is obtained such that the function can be reconstructed from the sampling values uniquely and stably.
