| Abstract: | Fisrtly, we use B-spline wavelet to de-noise the great amount of data from measurement with noise, and then use the curvatures of scattered data as the objects to carry out multiresolution analysis, thus we can get the high frequency coefficient. Therefore we can compress the data by sampling the original data according to the high frequency coefficients under a certain threshold. |

| Keywords: | wavelets multiresolution analysis reverse engineering data compression |
