Image Details
Caption: Figure 9.
From left to right are histograms of CPR, entropy, and mean alpha angle for interior and exterior regions of two anomalous craters “1”, “2,” and a fresh crater shown in the top ((a)–(c)), middle ((d)–(f)), and bottom ((g)–(i)) rows, respectively. Note the differences in the distributions of the entropy and alpha angle values compared to those of CPR for each crater region. The polygons shown in the interior and exterior regions of the craters as shown in Figure 11(b) are used to generate these histograms.
