| Abstract: |
| A kind of B spline wavelet is constructed by using B-spline function and the idea of multi-resolution analysis(MRA).The new method has simple expressions and the two scales equences are easily obtained in addition to many good properties such as symmetry and semi orthogonal,which is propitious to resolving practical problems. |
| Key words: wavelet B-spline multi-resolution analysis transfer function two scale sequences |
