Figure 6
Paganin-filtered images corresponding to the parameter values ℓstd and
lrmin listed in Table 1 . For each image, the central line profile is shown beneath the panel, and the corresponding histogram appears in the lower-left corner, aiding visual assessment of contrast and noise. Accompanying line-profile plots show the noisy unfiltered profile (blue line) and the filtered profile obtained using the near-optimal proposed filter value (red line). |
