Took the image, and zoomed in. Then inverted the color to get more contrast, enhanced the distribution of the colors and then re-inverted to get a more true representation.
After doing that , it brings out the contrast in the surrounding objects. And you can clearly see a grave marker, and another stone behind. And what looks like something horizontal, I can't tell if its a stone or a dirt pathway giving off some heat.
Although in front of the rear stone there appears to be some sort of humanoid figure.
