摘要
首先对小波分析的基本原理作了简要介绍,然后从图象信号完全重建的角度对几种小波基进行总结。着重指出:对于子带分解的小波基等价于在正则条件下,设计滤波器组;最后给出:Daubechies基的小波生成算法及实验结果。
Based on the brief introduction of the principle of wavelet analysis,a summary of several typical wavelet bases from the point of view of perfect reconstruction of an image is given.It is emphasized that designing wavelet bases which are used to decompose the image into sub band form is equivalent to designing a fliters with perfect or nearly perfect property.The generating algorithm corresponding to Daubechies bases and some simulation results are also show in this paper.
