| Abstract: | We presents a method based on AIC criterions to determine its decomposition scale,that is,the decomposition scale is determined based on the minimum information of the denoising data,on which the actual deformation precision can be calculated based.Finally,an example is given to illuminate that this method can preserve the deformation signal better with denoising,with which the actual deformation precision can be calculated more exactly. |
