I have been following comments from a small handful of your blog readers claiming that there are images of coins over the eyes. These claims are fraught with difficulty. Those who tilt LCD computer screens or enhance photographs exhibit a breathtaking ignorance of how the technology they use works. What you must do is only use technically superior full color images, the color in order to help identify invalid image parts such as dirt, fiber anomalies, blood and foreign particulate matter. Then you must develop analytical methods and tools that don’t rely on the vagaries of human visual perception or individual judgment. For now, it is utterly foolish to claim there are any coin images.
Flowers anyone? Lettering? Other things?
