小波框架的研究

Research on wavelet frames

讨论了框架的一般特性，并着重研究框架的冗余性．结果表明，采用冗余的小波框架进行离散小波重构，其重构误差比采用正交基实现的重构误差要小．

The generalities about frames are discussed with emphasis on the redundancy in frames. The result shows that the error in wavelet reconstruction with redundant frames is less than that with orthonormal bases.
