At 21:52:53 UTC Mastcam Left captured these rocks with an incredibly complex surface and not at all eroded!
Another example of rocks that should have had an extremely smooth surface and instead show a very high level of roughness, with almost “cauliflower” structures, as if they had been encrusted by something grown on their surfaces.
Also note the streaks of color present on the ground, with the well-known blue-greenish colorations, also present in part on the rocks themselves.
The original image is a black and white encoding of the Bayer mask that has been converted to color through a process called “debayering” or “demosaicing”. In addition, the photo has undergone noise reduction due to Jpeg compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.
