Fig. 9. Effect of padding on Wiener deconvolution for cropped measurement.
Top row shows the measurement while the bottom row shows the corresponding Wiener reconstruction. (a) Full measurement. Red box indicates the cropped out region. (b) Zero padded measurement and the corresponding reconstruction. (c) Replicate padded measurement and the corresponding reconstruction. (d) Smoothened replicate padded measurement along with the corresponding reconstruction. Line artifacts are significantly reduced in (d) which is used in this work.
