Fig. 4.

Application to color images. (A) Intact natural image with RGB color channels. (B) Image with color channels degraded independently. (C) Image with color channels degraded identically. Note that the color palette is preserved in C but not B. This can most easily be seen by the examining the body of the wombat, which is tannish/brown in both A and C but mottled with red, green, and blue patches in B. Lowercase a-c show a zoomed-in view of the images for closer examination. Source photo from author A.M.P.
