My Findings
Mars Fossils - Photographic Evidence Continued
Using these five images, I performed the frame stacking operation. This gave a much larger set of data to draw on to create a new image with higher resolution and less noise.

Using these five
images from the NASA data, I scaled them to match sizes, then overlaid
them using the frame stacking method. This resulted in a single
frame that had the image data of all five images, minus almost all of
the noise.
Even with this new image, though, there were limits to what could be seen. I determined that there were four radial lines, and that they were clearly symmetrical and of the same scale. The rounded feature at the top of the triangle turned out to be roughly circular, and topped with other, shorter line segments. Once again, all lines are of the same width, something that is extremely unlikely in erosion! |
After adding the frames together and performing a sharpening routine, this is the resulting image.

This is an
excellent improvement over the previous images, as it reveals far more
than I expected to see. The sharpness and clarity is much better,
and other subtle features have been revealed. Note the left side
shows a groove with regular depressions in it. The right top also
shows a groove, one that mirrors the position and size of the left one.
One nagging thing was the shadow- shadows are not hard to get rid of with simple methods, and that would improve the extraction of other details. If I were to subtract the shadows out, I could probably get even more information that is hidden in the image. In fact, shadow extraction is so simple that it can be applied to almost any image in a matter of seconds. I decided to try it on this image, as well as some of the earlier ones. |
Before proceeding to the other processing steps, I wanted to look at the newer data and see if anything stood out. This yielded some amazing things on the following pictures.
