| Abstract: | 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. |

| Keywords: | wavelet bases design fliters reconstruction of image |
