Optimum correction method based on overall performance score (OP) for weightings wres, wsmooth, wsignal and wASR. (a) The correction method that gives highest OP. (b) The characteristic filter size used with this correction method to achieve the highest OP. For each ternary plot, the weighting not shown on the axes is set to zero. Since interpolation between irregularly spaced points is a complex spatially variant filter, the characteristic filter size is not well defined, so it is represented as zero in the graphs. Speed is not included in the OP since it is possible to optimise speed independently. We do not show the trade off between resolution, smoothness and ASR, since in all combinations interpolation gives the best overall performance. Gaussian filtering (sky blue), median filtering (bluish green), Fourier filtering (orange), physical blurring (vermillion), interpolation (blue).
