| 摘要 |
Implementations described herein provide methods and devices for interpolating or estimating data from previously acquired data. Furthermore, implementations described herein calculate optimum interpolation operators by maximizing the spatial bandwidth of interpolation operators within a specified acceptable mean square error. According to one implementation, spatial bandwidth may be maximized by selecting a local grid within a global grid having nodes corresponding to desired interpolation locations. According to another implementation, spatial bandwidth may be maximized by specifying maximum wave numbers when calculating interpolation operators. |
