Abstract

A method for determining measurements of a surface includes determining a trend for a plurality of measurements and determining, for each of at least one of the plurality of measurements, an associated residual between the trend and the measurement and determining, for each of at least one of the associated residuals, an interpolated value for the residual. The method also includes comparing, for each of the at least one associated residuals, the residual to the interpolated value of the residual to determine whether a measurement associated with the residual is anomalous. In response to determining that a measurement associated with the residual is anomalous, the anomalous measurement is discarded. The remaining measurements then represent the surface of interest. The system includes a processor for executing a program of the method. Further, the system includes memory, an input device, and an output device.
