The centrosysmmetric B-spline wavelets have simple expressions and the two-scale sequences are easily obtained.
因为不需要计算傅立叶逆变换，因此两尺度序列更易于求得。
This algorithm makes good use of the B-Spline functions well performance in edge estimation and wavelets multi-scales character. The experimental results are satisfactory.
